Java program using nested if

import java.util.*;
class nestedif
{
public static void main (String arg[])
{
Scanner in = new Scanner (System.in);
int a,b,c,d;
System.out.print ("\n\t Enter first number = ");
a=in.nextInt();


System.out.print ("\n\t Enter second number = ");
b=in.nextInt();

System.out.print ("\n\t Enter third number = ");
c=in.nextInt();

 if (a<b)
{
if (a<c)
System.out.println ("\n\t First number is smallest ");
else
System.out.println ("\n\t First number is not smallest");
}
else if (b<a)
{
if (b<c)
System.out.println ("\n\t Second number is smallest ");
else
System.out.println ("\n\t Second number is not smallest ");
}
else
System.out.println ("\n\t Third number is smallest ");

}
}

Note: 
          In the above program, after entering the values, computer will check that either a is less than b or not. If it is than it will check the other if condition in its block. If it is true then it will show the message 
"First number is smallest" otherwise the statement associated with else will be executed and rest of the code will be bypassed.
