17 Aug Java Program to display the minimum and maximum value of primitive data types

Java Datatype has a range, i.e. represented by a minimum and maximum. Primitive Data Types include the byte, short, boolean, int, long, float, double and char type.

Following are the minimum and maximum value of primitive data types in Java:

• byte: An 8-bit signed two’s complement integer
  Minimum Value: -128
  Maximum Value: 127
• short: A 16-bit signed two’s complement integer
  Minimum Value: -32768
  Maximum Value: 32767
• int: A 32-bit signed two’s complement integer
  Minimum Value: -2,147,483,648
  Maximum Value: 2,147,483,647
• long: A 64-bit two’s complement integer
  Minimum Value: -9,223,372,036,854,775,808
  Maximum Value: 9,223,372,036,854,775,807
• char: A single 16-bit Unicode character.
  Minimum Value: ‘\u0000’ (or 0)
  Maximum value: ‘\uffff’
• float: A single-precision 32-bit IEEE 754 floating point
  Minimum Value: 1.4E-45
  Maximum Value: 3.4028235E38
• double: A double-precision 64-bit IEEE 754 floating point
  Minimum Value: 4.9E-324
  Maximum Value: 1.7976931348623157E308
• boolean: Possible values, TRUE and FALSE.

Let’s now see some examples to display the minimum and maximum value of primitive data types:

Example 1

public class Example {

  public static void main(String[] args) {
    
    short a = 10;
    byte b = 5;
    
    System.out.println("Value of a = " + a);
    System.out.println("short type MAXIMUM Value = " + Short.MAX_VALUE);
    System.out.println("short type MINIMUM Value = " + Short.MIN_VALUE);
    
    System.out.println("\nValue of b = " + b);
    System.out.println("byte type MAXIMUM Value = " + Byte.MAX_VALUE);
    System.out.println("byte type MINIMUM Value = " + Byte.MIN_VALUE);
  }
}

Output

Value of a = 10
short type MAXIMUM Value = 32767
short type MINIMUM Value = -32768

Value of b = 5
byte type MAXIMUM Value = 127
byte type MINIMUM Value = -128

Example 2

public class Example {

  public static void main(String[] args) {
    
    float a = 3.99f;
    double b = 10.99d;
    long c = 878768768L;
    
    System.out.println("Value of a = " + a);
    System.out.println("float type MAXIMUM Value = " + Float.MAX_VALUE);
    System.out.println("float type MINIMUM Value = " + Float.MIN_VALUE);
    
    System.out.println("\nValue of b = " + b);
    System.out.println("double type MAXIMUM Value = " + Double.MAX_VALUE);
    System.out.println("double type MINIMUM Value = " + Double.MIN_VALUE);
    
    System.out.println("\nValue of c = " + c);
    System.out.println("long type MAXIMUM Value = " + Long.MAX_VALUE);
    System.out.println("long type MINIMUM Value = " + Long.MIN_VALUE);
  }
}

Output

Value of a = 3.99
float type MAXIMUM Value = 3.4028235E38
float type MINIMUM Value = 1.4E-45

Value of b = 10.99
double type MAXIMUM Value = 1.7976931348623157E308
double type MINIMUM Value = 4.9E-324

Value of c = 878768768
long type MAXIMUM Value = 9223372036854775807
long type MINIMUM Value = -9223372036854775808
