For-each

Question

How I use for-each loop?

Answer 1

public static void main(String[] args){
int[] array = {2, 5, 9, 3, 4};

for(int x: array){
System.out.println(x);
}
}

The output will be:
2
5
9
3
4

The variable x is taking the values in the array.

Hi martin !
With java 8 specifications , java has added a new programming style of loop within Lists so just you have to check if ur JDK is grater or equal to 1.8 to use the below code :
public class ForEach{

public static void main(String [] args) {
List<Integer> array = new ArrayList<>();
array.add(1);
array.add(2);
array.add(3);
array.forEach(element -> {
System.out.println(element);
});
}}

// Output: 1
