For-Each loop

For-Each Loop:

• Introduce in jdk5.
• Used to traverse the elements of Collection and arrays.
• Reduce the probability of programming errors.
• Make code more readable.

Syntax:

for( (datatype/object) variable:value(array/collection) )

{

}

Example:

ArrayList al=new ArrayList();

al.add(12);al.add("sam");al.add(23);

for(Object obj:al)

{

System.out.println(obj);

}

InCase of Array:

int arr[]={12,23,89};

for(int a:arr){

          System.out.println(a);
}
