Does Java support goto?

Java does not support goto, it is reserved as a keyword just in case they wanted to add it to a later version.

Unlike C/C++, Java does not have goto statement, but java supports label.
The only place where a label is useful in Java is right before nested loop statements.
We can specify label name with break to break out a specific outer loop.
Similarly, label name can be specified with continue.

Using break with label in Java

// Java code to illustrate 
// using label  and break 
// instead of goto 
  
// file name: Main.java 
public class Main { 
    public static void main(String[] args) 
    { 
  
    // label for outer loop 
    outer: 
        for (int i = 0; i < 10; i++) { 
            for (int j = 0; j < 10; j++) { 
                if (j == 1) 
                    break outer; 
                System.out.println(" value of j = " + j); 
            } 
        } // end of outer loop 
    } // end of main() 
} // end of class Main 

Output:

value of j = 0

Using continue with label in Java

We can also use continue instead of break. See following program for example.

// Java code to illustrate 
// using label  and continue 
// instead of goto 
  
// file name: Main.java 
public class Main { 
    public static void main(String[] args) 
    { 
  
    // label for outer loop 
    outer:  
        for (int i = 0; i < 10; i++) { 
            for (int j = 0; j < 10; j++) { 
                if (j == 1) 
                    continue outer; 
                System.out.println(" value of j = " + j); 
            } 
        } // end of outer loop 
    } // end of main() 
} // end of class Main 

/div>

Output:

value of j = 0
value of j = 0
value of j = 0
value of j = 0
value of j = 0
value of j = 0
value of j = 0
value of j = 0
value of j = 0
value of j = 0

Explanation : Since continue statement skips to the next iteration in the loop, it iterates for 10 times as i iterates from 0 to 9. So the outer loop executes for 10 times and the inner for loop executes 1 time in each of the outer loop.
