Answer 1

Generally a for loop consists of 3 parts
1.initialization
2.condition
3.either a increment or decrement operator

But enhanced for loop is a bit different.
We use it in collections
Its syntax is like
for(classname object: referencevariable)
Here class name is the name of the class whose objects are taken into consideration for creating a collection
reference variable is the variable which points out my collection.
We will see an example which will clearly illustrate what is an enhanced for loop

import java.util.*;  
class  Testenhancedforloop{  
public static void main(String args[]){  
ArrayList<String> al=new ArrayList<String>();  
 al.add("Ravi");  
 al.add("Vijay");  
 al.add("Ravi");  
al.add("Ajay");  
 for(String obj:al)  
System.out.println(obj);  
 }  
}
