Hi Friend,

Try this:

```class ConversionExample
{
public static void main(String[] args)
{
int i=26;
Integer integer=new Integer(i);
String st=integer.toString();
int no=Integer.parseInt(st);
String str=Integer.toString(no);
Integer num=Integer.valueOf(str);
int in=num.intValue();
System.out.println("int to Integer= "+integer);
System.out.println("Integer to String= "+st);
System.out.println("String to int= "+no);
System.out.println("int to String= "+str);
System.out.println("Integer to String= "+st);
System.out.println("String to Integer= "+num);
System.out.println("Integer to int= "+in);
int max=Integer.MAX_VALUE;
int min=Integer.MIN_VALUE;
System.out.println("Minimum value of integer: "+min);
System.out.println("Maximum value of integer: "+max);
System.out.println("Binary: "+Integer.toBinaryString(in));

}
}
```

Thanks
