Jump statements in Java

Jump statements are the statements which transfers the control to another part of the program. There are 3 types of jump statements
1)break
2)continue
3)return

1)Using break statements
There are mainly 3 uses of break statement
           * It terminates a sequence in a switch statements.
           * It can be used to exit a loop
           * It can be used the civilized form of GO TO.

Example for exit a loop :
public class BreakLoop { public static void main(String[] args) { for(int i=1;i<=10;i++) {System.out.println("Inside for loop. count is "+i); if (i>=5) {System.out.println("executing break statement . count is "+i); break; } } System.out.println("Came out from for loop. "); }}

Output:

Example for form of Go TO:
Syntax:
break label;

where label is the name given to a block of code.

public class BreakLoop { public static void main(String[] args) { int i=1; first_block:{ second_block:{ third_block:{ System.out.println("third block "); if(i==1) break second_block; } System.out.println("second block ");//second block will not print } System.out.println("first block "); } }}

Output:

Using Continue:
In the iteration statement you can come up with a scenario as you need to continue with next iteration without executing the remaining statements in the loop body .In such scenario continue can be used.

Example:
public class ContinueLoop { public static void main(String[] args) { for(int i=1;i<=10;i++) { System.out.println("Inside for loop. count is "+i); if (i!=5) continue; System.out.println("This will execute only when i=5 .the value of i is "+i); } }}

Output:

 return statement:
The return statement is used to explicitly return from a method. It directly returns the control to the caller of the method.
We will discuss later about this with more examples.
