Coding Below

class WrapperTest
{
void inttest()
{
Integer i1=new Integer(42);
Integer i2=new Integer("42");
Integer i3=new Integer.valueOf("101011",2);
Integer i4=new Integer.valueOf("101011",8);
Integer i5=new Integer.valueOf("101011",16);

System.out.println(i1);
System.out.println(i2);
System.out.println(i3);
System.out.println(i4);
System.out.println(i5);

}

void floattest()
{
Float f1=new Float(3.14);
Float f2=new Float("3.14");
Float f3=new Float.valueOf("3.14f");

System.out.println(f1);
System.out.println(f2);
System.out.println(f3);
}

void booleantest()
{
Boolean b1=new Boolean(false);
Boolean b2=new Boolean("false");

System.out.println(b1);
System.out.println(b2);
}

public static void main(String arr[])
{
WrapperTest wt=new WrapperTest();
wt.inttest();
wt.floattest();
wt.booleantest();
}
}
