Continue Statement in Java

Java Continue Statement The Java continue statement is used to continue loop. It continues the current flow of the program and skips the remaining code at specified condition. In case of inner loop, it continues only inner loop. Syntax: jump-statement;     continue;    Java Continue Statement Example Example: public class ContinueExample {   public static void main(String[] args) {       for(int i=1;i<=10;i++){           if(i==5){               continue;           }           System.out.println(i);       }   }   }   Output: 1 2 3 4 6 7 8 9 10 Java Continue Statement with Inner Loop It continues inner loop only if you use continue statement inside the inner loop. Example: public class ContinueExample2 {   public static void main(String[] args) {               for(int i=1;i<=3;i++){                         for(int j=1;j<=3;j++){                             if(i==2&&j==2){                                 continue;                             }                             System.out.println(i+" "+j);                         }                 }     }   }   Output: 1 1 1 2 1 3 2 1 2 3 3 1 3 2 3 3

Break Statement in Java

Java Break Statement

The Java break is used to break loop or switch statement. It breaks the current flow of the program at specified condition. In case of inner loop, it breaks only inner loop.

Syntax:

1. jump-statement;    
2. break;   

Java Break Statement with Loop

Example:

1. public class BreakExample {  
2. public static void main(String[] args) {  
3.     for(int i=1;i<=10;i++){  
4.         if(i==5){  
5.             break;  
6.         }  
7.         System.out.println(i);  
8.     }  
9. }  
10. }  

Output:

1
2
3
4

Java Break Statement with Inner Loop

It breaks inner loop only if you use break statement inside the inner loop.

Example:

1. public class BreakExample2 {  
2. public static void main(String[] args) {  
3.             for(int i=1;i<=3;i++){    
4.                     for(int j=1;j<=3;j++){    
5.                         if(i==2&&j==2){    
6.                             break;    
7.                         }    
8.                         System.out.println(i+" "+j);    
9.                     }    
10.             }    
11. }  
12. }  

Output:

1 1
1 2
1 3
2 1
3 1
3 2
3 3
