Foreach Loop In JAVA

Java For-each or Enhanced For Loop

The for-each loop is used to traverse array or collection in java. It is easier to use than simple for a loop because we don't need to increment value and use subscript notation.

It works on elements basis not index. It returns elements one by one in the defined variable.

Syntax : 

for(Type var:array){  
//code to be executed 
//syntax for foreach loop 
}  

Example Foreach Loop 1:

public class ForEachDemo   
{  
    public static void main(String[] args)   
    {  
        int[] arr = { 1, 2, 3, 4 };  
        for (int i : arr)   
        {  
            System.out.println(i);  
        }  
    }  
}  

OutPut

Example Foreach : (PROGRAM TO PRINT ARRAY VALUES WITH USER INPUT)

//PROGRAM TO PRINT ARRAY VALUES WITH SCANNER
import java.util.Scanner;  
public class ForEachDemo   
{  
    public static void main(String arng[]) {  
        int value[] = new int[5];  
        Scanner data = new Scanner(System.in);  
        float sum = 0;  
        System.out.println("Enter 5 element of array");  
        // Enhanced for loop  
        for (int i : value) {  
            i = data.nextInt();  
            sum = sum + i;  
        }  
        System.out.println("Sum is " +sum);  
    }  
}  

Output :

Enter 5 element of array
5
5
5
5
5

Sum is 25.0
