break and continue are java keywords to skip control flow statements depending on certain condition.
break and continue have 2 forms, labeled and unlabeled
Break
An unlabeled break statement terminates the innermost switch, for, while, or do-while statement, but a labeled break terminates an outer statement.
Unlabeled break statement usage
public class BreakTest {
public static void main(String[] args) {
System.out.print("I: ");
for (int i = 1; i <= 5; i++) {
if (i == 3){
break;
//if condition true, control moves out of loop
}
System.out.print(i+" ");
}
}
}
OutPut
I: 1 2
labeled break statement usage
refer Exit from nested for loop
Continue
The continue statement skips the current iteration of a for, while , or do-while loop, but a labeled continue statement skips the current iteration of an outer loop marked with the given label.
Unlabeled continue statement usage
package trypkg;
public class ContinueTest {
public static void main(String[] args) {
System.out.print("I: ");
for (int i = 1; i <= 5; i++) {
if (i == 3){
continue;
//if condition true, skips current iteration and moves to next iteration
}
System.out.print(i+" ");
}
}
}
OutPut:
I: 1 2 4 5
Labeled continue statement usage
public class ContinueTestLabeled {
public static void main(String[] args) {
int arr[] = {2, 3, 4, 54, 33, 73, 5};
System.out.println("Odd numbers are: ");
loop:
for(int i=0 ; i<arr.length ; i++){
if(arr[i] % 2 == 0){
continue loop;
}
System.out.println(arr[i]);
}
}
}
OutPut:
Odd numbers are:
3
33
73
5
