Break

In Python, the keyword break causes the program to exit a loop early. break causes the program to jump out of for loops even if the for loop hasn't run the specified number of times.break causes the program to jump out of while loops even if the logical condition that defines the loop is still True.

An example using break in a for loop is below.

In [1]:

for i in range(100):
    print(i)
    if i == 3:
        break
print('Loop exited')

When the loop hits i=3, break is encountered and the program exits the loop.

An example using break in a while loop is below.

In [2]:

while True:
    out = input('type q to exit the loop: ')
    if out == 'q':
        break
print('Loop exited')

type q to exit the loop: no
type q to exit the loop: q
Loop exited

Continue

In Python, the keyword continue causes the program to stop running code in a loop and start back at the top of the loop. Remember the keyword break cause the program to exit a loop. continue is similar, but continue causes the program to stop the current iteration of the loop and start the next iteration at the top of the loop.

A code section that uses continue in a for loop is below.

In [3]:

for i in range(4):
    if i==2:
        continue
    print(i)

When the code section is run, the number 2 is not printed. This is because when i=2 the program hits the continue statement. Therefore, the line print(i) isn't run when i=2. Then the program starts back up at the start of the loop with the next number i=3.

The break and continue statements are the jump statements that are used to skip some statements inside the loop or terminate the loop immediately without checking the test expression. These statements can be used inside any loops such as for, while, do-while loop.

Break: The break statement in java is used to terminate from the loop immediately. When a break statement is encountered inside a loop, the loop iteration stops there, and control returns from the loop immediately to the first statement after the loop. Basically, break statements are used in situations when we are not sure about the actual number of iteration for the loop, or we want to terminate the loop based on some condition.

Syntax :

break;

In Java, a break statement is majorly used for:

To exit a loop.
Used as a “civilized” form of goto.
Terminate a sequence in a switch statement.

Using break to exit a loop

Using break, we can force immediate termination of a loop, bypassing the conditional expression and any remaining code in the body of the loop. When we use break inside the nested loops, it will only break out of the innermost loop.

Example:

Java

class GFG {

public static void main(String[] args)

{

for (int i = 0; i < 10; i++) {

if (i == 5)

break;

System.out.println("i: " + i);

}

System.out.println("Out of Loop");

}

Output

i: 0
i: 1
i: 2
i: 3
i: 4
Out of Loop

Using break as a Form of Goto

Java does not have a goto statement because it provides a way to branch in an arbitrary and unstructured manner. Java uses a label. A Label is used to identify a block of code.

Syntax:

label:
{
  statement1;
  statement2;
  statement3;
  .
  .
}

Now, the break statements can be used to jump out of the target block. We cannot break to any label which is not defined for an enclosing block.

Syntax:

break label;

Example:

Java

class GFG {

public static void main(String args[])

{

first:

for (int i = 0; i < 3; i++) {

second:

for (int j = 0; j < 3; j++) {

if (i == 1 && j == 1) {

break first;

}

System.out.println(i + " " + j);

}

Using break to terminate a sequence in a switch statement.

The switch statement is a multi-way branch statement. It provides an easy way to dispatch execution to different parts of code based on the value of the expression. The break statement is used inside the switch to terminate a statement sequence. The break statement is optional. If omitted, execution will continue on into the next case.

Syntax:

switch (expression)
{
  case value1:
    statement1;
    break;
  case value2:
    statement2;
    break;
  .
  .
  case valueN:
    statementN;
    break;
  default:
    statementDefault;
}

Example:

Java

class GFG {

public static void main(String args[])

{

int i = 2;

switch (i) {

case 0:

System.out.println("i is zero.");

break;

case 1:

System.out.println("i is one.");

break;

case 2:

System.out.println("i is two.");

break;

default:

System.out.println("Invalid number");

}

Continue:

The continue statement in Java is used to skip the current iteration of a loop. We can use continue statement inside any types of loops such as for, while, and do-while loop. Basically continue statements are used in the situations when we want to continue the loop but do not want the remaining statement after the continue statement.

Syntax:

continue;

Using continue to continue a loop

Using continue, we can skip the current iteration of a loop and jumps to the next iteration of the loop immediately.

Example:

Java

class GFG {

public static void main(String args[])

{

for (int i = 0; i < 10; i++) {

if (i == 2)

continue;

System.out.print(i + " ");

}

Using continue as a labelled continue statement

The unlabeled continue statement is used to continue the innermost loop. However, since JDK 1.5 java introduces another feature known as labelled continue statement. We can use a labelled continue statement to continue the outermost loop.

Example:

Java

class GFG {

public static void main(String args[])

{

first:

for (int i = 0; i < 3; i++) {

second:

for (int j = 0; j < 3; j++) {

if (i == 1 && j == 1) {

continue first;

}

System.out.println(i + " " + j);

}

Output

Difference between break and continue:

Break	Continue
The break statement is used to terminate the loop immediately.	The continue statement is used to skip the current iteration of the loop.
break keyword is used to indicate break statements in java programming.	continue keyword is used to indicate continue statement in java programming.
We can use a break with the switch statement.	We can not use a continue with the switch statement.
The break statement terminates the whole loop early.	The continue statement brings the next iteration early.
It stops the execution of the loop.	It does not stop the execution of the loop.

Which statement is used to stop current iteration of the loop?

The break statement is used to terminate the execution of the current loop. Whenever there is a need to end the loop, you need to add the break statement. Once the break statement is met, all the iterations are stopped, and the control is shifted outside the loop.

How do you stop a current iteration in Python?

The Python break statement immediately terminates a loop entirely. Program execution proceeds to the first statement following the loop body. The Python continue statement immediately terminates the current loop iteration.

What is the keyword for ending the current iteration of a loop and start a new iteration in Python?

The continue keyword is used to end the current iteration in a for loop (or a while loop), and continues to the next iteration.

Which keyword will stop the current iteration of a loop and move on to the next iteration?

The purpose the break statement is to break out of a loop early. For example if the following code asks a use input a integer number x. If x is divisible by 5, the break statement is executed and this causes the exit from the loop.
