break
- two forms of break
1. Labelled
2. Unlabelled
- the Unlabelled break is normally used in switch while the Labelled break is mostly used to get out in an outer loop coming from an inner loop.
================================
class TestLabelledBreak{
public static void main(String[] args){
String[] name = {
{"La", "Le", "Li", "Lo", "Lu"},
{"Ma", "Me", "Mi", "Mo", "Mu"}
};
loop1:
for(int i=0; i<2; i++){
for(int j=0; j=5; j++){
if(name[i][j] = "Mi"){
break loop1;
}
System.out.print(name[i][j]);
}
System.out.println();
}
}
}
================================
Result:
LaLeLiLoLu
MaMe
continue
- it is same as the break except it does not end the loop but just skips the loop and proceed to the next loop.
- this has labelled and unlabelled forms too.
return
- when your method has a return data type, you can use this return keyword followed by that value.
================================
class TestReturn{
private int addNumbers(int x, int y){
return x + y;
}
private void displayHello(){
System.out.println("Hello");
return;
}
public static void main(String[] args){
int n = 4;
int m = 8;
TestReturn t = new TestReturn();
int total = t.addNumbers(n, m);
System.out.println(total);
t.displayHello();
}
}
================================

Hello
The first return returns an int type. The return is followed by adding two integers.
The second returns nothing. You can use a return with no value to exit the method.
