In this program you will learn about Conversion (wrapper class)Integer Number Object to (primitive data type) int
public class WrapperclassToPemitiveDataType{
public static void main(String args[]){
//Converting Integer to int
Integer n=new Integer(15);
int i=n.intValue();//converting Integer to int
int j=n;//unboxing, now compiler will write n.intValue() internally
System.out.println(n+" "+i+" "+j);
}
}

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
