The length of java basic data types

The maximum value limit and minimum value limit of Java's basic data types can be easily known by writing a small program.

Test the maximum and minimum values ​​of Integer, Long, Float and Double. The code is as follows:



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

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

System.out.println("Float.MIN_VALUE = " + Float.MIN_VALUE);
System.out.println("Float.MIN_NORMAL = " + Float.MIN_NORMAL );
System.out.println("Float.MAX_VALUE = " + Float.MAX_VALUE);

System.out.println("Double.MAX_VALUE = " + Double.MAX_VALUE);
System.out.println("Double .MIN_VALUE = " + Double.MIN_VALUE);
}


The output result is as follows:
Integer.MIN_VALUE = -2147483648 (10 bits)
Integer.MAX_VALUE = 2147483647
Long.MIN_VALUE = -922 3372036854775808 (19 digits)
Long. MAX_VALUE = 9223372036854775807
Float.MIN_VALUE = 1.4E-45
Float.MIN_NORMAL = 1.17549435E-38
Float.MAX_VALUE = 3.4028235E38
Double.MAX_VALUE = 1.7976931348623157E308
Double.MIN_VALUE = 4.9E-324
