Scanner in = new Scanner(System.in) ;
System.out.print("Enter a number: ") ;
Num1 = in.nextInt() ;
System.out.print("Enter a number: ") ;
Num2 = in.nextInt() ;
System.out.print("Enter a number: ") ;
Num3 = in.nextInt() ;
If (num1 > num2)
{
If (num1 > num3)
{
System.out.println(num1) ;
}
Else
{
System.out.println(num3) ;
}
}
Else
{
If (num2 > num3)
{
System.out.println(num2) ;
}
Else
{
System.out.println(num3) ;
}
}
