The size of the datatype is given by (name of datatype).SIZE. In java the maximum value it can store is given by (data type name). MAX_VALUE. The minimum value it can store is given by (Name of data type).MIN_VALUE.

Always write first word of data type in capital.

Example:

1. Use Float.SIZE to print the size of float data type.
2. If you would like to print the dimensions and value of the Byte use the subsequent code
    

// Print size, minimum value and maximum
// value of Byte data types in java
import java.io.*;

class ValuesOfByte {
	public static void main(String[] args)
	{
		System.out.println("Byte\t" + Byte.SIZE + "\t"
						+ Byte.MIN_VALUE + "\t"
						+ Byte.MAX_VALUE);
	}
}

Output

Byte    8    -128    127

3. To print the dimensions , the utmost and minimum value of all primitive data type use the subsequent code

// Print size, minimum value and
// maximum value of data types in java
public class RangeOfDataTypes {
	public static void main(String args[])
	{
		System.out.println(
			"S.No.\t Data Type\t Size\t Min. Value\t\t Max. Value\t");
		System.out.println("1\t Byte\t\t" + Byte.SIZE
						+ "\t" + Byte.MIN_VALUE
						+ "\t\t\t" + Byte.MAX_VALUE);
		System.out.println("2\t Short\t\t" + Short.SIZE
						+ "\t" + Short.MIN_VALUE
						+ "\t\t\t" + Short.MAX_VALUE);
		System.out.println("3\t Integer\t" + Integer.SIZE
						+ "\t" + Integer.MIN_VALUE
						+ "\t\t" + Integer.MAX_VALUE);
		System.out.println("4\t Float\t\t" + Float.SIZE
						+ "\t" + Float.MIN_VALUE
						+ "\t\t\t" + Float.MAX_VALUE);
		System.out.println("5\t Long\t\t" + Long.SIZE
						+ "\t" + Long.MIN_VALUE + "\t"
						+ Long.MAX_VALUE);
		System.out.println("6\t Double\t" + Double.SIZE
						+ "\t" + Double.MIN_VALUE
						+ "\t\t" + Short.MAX_VALUE);
		System.out.println("7\t Character\t"
						+ Character.SIZE);
	}
}

Output:
