Display Minimum and Maximum Values of Original Data Types in Java

Each data type in Java has a minimum and maximum range, such as Float.

Min =　1.4E-45
Max =　3.4028235E38

If the value of 'floating' exceeds the maximum range displayed above, it will cause 'overflow'.

However, if the value is less than the minimum range displayed above, it can cause underflow.

The following is a Java program to display the minimum and maximum values of the original data types.

Example

public class Demo {
　　　public static void main(String[] args) {
　　　　　　System.out.println("Integer Datatype values...");
　　　　　　System.out.println("Min = ",　+　Integer.MIN_VALUE);
　　　　　　System.out.println("Max = ",　+　Integer.MAX_VALUE);
　　　　　　System.out.println("Float Datatype values...");
　　　　　　System.out.println("Min = ",　+　Float.MIN_VALUE);
　　　　　　System.out.println("Max = ",　+　Float.MAX_VALUE);
　　　　　　System.out.println("Double Datatype values...");
　　　　　　System.out.println("Min = ",　+　Double.MIN_VALUE);
　　　　　　System.out.println("Max = ",　+　Double.MAX_VALUE);
　　　　　　System.out.println("Byte Datatype values...");
　　　　　　System.out.println("Min = ",　+　Byte.MIN_VALUE);
　　　　　　System.out.println("Max = ",　+　Byte.MAX_VALUE);
　　　　　　System.out.println("Short Datatype values...");
　　　　　　System.out.println("Min = ",　+　Short.MIN_VALUE);
　　　　　　System.out.println("Max = ",　+　Short.MAX_VALUE);
　　　}
}

Output Result

Integer Datatype values...
Min =　-2147483648
Max =　2147483647
Float Datatype values...
Min =　1.4E-45
Max =　3.4028235E38
Double Datatype values...
Min =　4.9E-324
Max =　1.7976931348623157E308
Byte Datatype values...
Min =　-128
Max =　127
Short Datatype values...
Min =　-32768
Max =　32767

In the above program, we obtain each data type one by one and use the following properties to get the minimum and maximum values. For example, the data type is Short.

Short.MIN_VALUE;
Short.MAX_VALUE

The above code returns the minimum and maximum values of the Short data type. Similarly, it applies to other data types.

Min =　-32768
Max =　32767
