Foreach loop in Java

Hello friends how are you, today in this blog i will teach you what is foreach loop, syntax of foreach loop , how foreach loop works and many programs using foreach loop in a very simple way. 

Let's start 

Foreach loop in Java

Syntax: 

• It is a special type of loop which is used mostly with array.
• It stores each element of array in a variable and executes the body of loop.
• It starts with for keyword like a normal for loop.
• If you want to access all the elements of array in a very simple then this loop is very useful.

Example 1:Program with foreach loop

Here in the below program we are going to print all the elements of an array using foreach loop. As we know that we can access the elements of an array using index number which starts from zero. But here the important point is that we can access all the elements of array without index using foreach loop.

class Easy
{
 public static void main(String[] args) 
 {
  //array declaration
  int ar[]={10,50,60,80,90};
  for (int element:ar) 
   System.out.print(element+" ");       
 }
}
/*
### Output ###
10 50 60 80 90
*/

Here in the above program there is an array ar which have 5 elements 10 50 60 80 90 and here foreach loop are using to print the elements. 

Example 2:Same program with for loop

Here  i am going to print all the elements of same array using for loop so that you could understand this in a very simple way.

class Easy
{
 public static void main(String[] args) 
 {
  //array declaration
  int ar[]={10,50,60,80,90};
  for (int i = 0; i <ar.length; i++) 
   System.out.print(ar[i]+" ");       
 }
}
/*
### Output ###
10 50 60 80 90
*/
