The Java programming language is a strongly-typed language and it consist of eight primitive data types (byte, short, int, long, float, double, boolean, char). For more about java primitive data type, please visit http://java.sun.com/docs/books/tutorial/java/nutsandbolts/datatypes.html

Well, sometime we really need to know what is the limit of the primitive types in java. With following simple code, we can print out the limit of each of the java primitive data types (except boolean and char) :)

public class PrintTypeLimit
{
    public static void main(String args[]) {
 
        System.out.println("Min byte value   = " + Byte.MIN_VALUE);
        System.out.println("Max byte value   = " + Byte.MAX_VALUE);
        System.out.println("Min short value  = " + Short.MIN_VALUE);
        System.out.println("Max short value  = " + Short.MAX_VALUE);
        System.out.println("Min int value    = " + Integer.MIN_VALUE);
        System.out.println("Max int value    = " + Integer.MAX_VALUE);
        System.out.println("Min long value    = " + Long.MIN_VALUE);
        System.out.println("Max long value    = " + Long.MAX_VALUE);
        System.out.println("Min float value  = " + Float.MIN_VALUE);
        System.out.println("Max float value  = " + Float.MAX_VALUE);
        System.out.println("Min double value = " + Double.MIN_VALUE);
        System.out.println("Max double value = " + Double.MAX_VALUE);
    }
}


Output

Min byte value   = -128
Max byte value   = 127
Min short value  = -32768
Max short value  = 32767
Min int value    = -2147483648
Max int value    = 2147483647
Min long value    = -9223372036854775808
Max long value    = 9223372036854775807
Min float value  = 1.4E-45
Max float value  = 3.4028235E38
Min double value = 4.9E-324
Max double value = 1.7976931348623157E308
