Java consists of eight primitive data types which are byte, short, int, long, float, double, boolean and char. A primitive is named by a reserved keyword and is predefined by the language. Primitive values do not share state with other primitive values. We can get the min and max value of primitive data types using the below code
public class MinMaxValue{
public static void main(String args[]) {
System.out.println("byte min value = " + Byte.MIN_VALUE);
System.out.println("byte max value = " + Byte.MAX_VALUE);
System.out.println("short min value = " + Short.MIN_VALUE);
System.out.println("short max value = " + Short.MAX_VALUE);
System.out.println("int min value = " + Integer.MIN_VALUE);
System.out.println("int 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 max value = " + Float.MAX_VALUE);
System.out.println("double min value = " + Double.MIN_VALUE);
System.out.println("double max value = " + Double.MAX_VALUE);
System.out.println("character min value = " + (int) Character.MIN_VALUE);
System.out.println("character max value = " + (int) Character.MAX_VALUE);
}
}
output:-
byte min value = -128 byte max value = 127 short min value = -32768 short max value = 32767 int min value = -2147483648 int max value = 2147483647 long min value = -9223372036854775808 long max value = 9223372036854775807 float min value = 1.4E-45 float max value = 3.4028235E38 double min value = 4.9E-324 double max value = 1.7976931348623157E308 character min value = 0 character max value = 65535
The boolean data type has only two possible values: true and false. So using the above code we can get the min and max value of primitive data types in java.
