BigDecimal shortValueExact() Method in Java

The java.math.BigDecimal.shortValueExact() is an inbuilt method in java that converts this BigDecimal to a short, checking for lost information. If this BigDecimal has a nonzero fractional part or is out of the possible range for a short result then an ArithmeticException is thrown.

Syntax:

public short shortValueExact()

Parameters: The method does not accepts any parameter.

Return value: This method returns the short value of the BigDecimal Object.

Below programs illustrates the above mentioned method:
Program 1:

// Program to demonstrate shortValueExact() method of BigDecimal

import java.math.*;

public class gfg {

    public static void main(String[] args)
    {

        BigDecimal b1 = new BigDecimal("457");
        BigDecimal b2 = new BigDecimal("4785");

        // Assigning the short value of BigDecimal objects b1 and b2
        // to short s1, s2 respectively
        short s1 = b1.shortValueExact();
        short s2 = b2.shortValueExact();

        // Printing s1, s2 values
        System.out.println("Exact short value of " + b1 + " is " + s1);
        System.out.println("Exact short value of " + b2 + " is " + s2);
    }
}

Output:

Exact short value of 457 is 457
Exact short value of 4785 is 4785

Program 2:

// Program to demonstrate shortValueExact() method of BigDecimal


import java.math.*;

public class gfg {

    public static void main(String[] args)
    {

        BigDecimal b1 = new BigDecimal("127");
        BigDecimal b2 = new BigDecimal("1455");

        // assign the short value of BigDecimal objects b1 and b2
        // to short s1, s2 respectively
        short s1 = b1.shortValueExact();
        short s2 = b2.shortValueExact();

        // print s1, s2 values
        System.out.println("Exact short value of " + b1 + " is " + s1);
        System.out.println("Exact short value of " + b2 + " is " + s2);
    }
}

Output:

Exact short value of 127 is 127
Exact short value of 1455 is 1455
