/*
 * The Number classes include constants and useful class 
 * methods.The MIN_VALUE and MAX_VALUE constants contain 
 * the smallest and largest values that can be contained 
 * by an object of that type.

    public static void main(String[] args)
    {
        System.out.println("Byte Max Value = " + Byte.MAX_VALUE);
        System.out.println("Byte Min Value = " + Byte.MIN_VALUE);

        System.out.println("Short Max Value = " + Short.MAX_VALUE);

        System.out

        System.out

        System.out.println("Long Max Value = " + Long.MAX_VALUE);
        System.out.println("Long Min Value = " + Long.MIN_VALUE);

        System.out.println("Float Max Value = " + Float.MAX_VALUE);
        System.out.println("Float Min Value = " + Float.MIN_VALUE);

        System.out.println("Double Max Value = " + Double.MAX_VALUE);

Output

Byte Max Value = 127
Byte Min Value = -128
Short Max Value = 32767
Short Min Value = -32768
Integer Max Value = 2147483647
Integer Min Value = -2147483648
Long Max Value = 9223372036854775807
Long Min Value = -9223372036854775808
Float Max Value = 3.4028235E38
Float Min Value = 1.4E-45
Double Max Value = 1.7976931348623157E308
Double Min Value = 4.9E-324
