Introduction

Converting a String to a Short in Java is a common task that can be useful in various scenarios, such as parsing user input, reading data from files, or handling configuration parameters. In Java, this conversion can be done using several methods. This blog post will explore different methods to convert a String to a Short in Java.

1. Using Short.parseShort()

The Short.parseShort() method parses the string argument as a signed decimal short.

Example:

public class StringToShortUsingParseShort {
    public static void main(String[] args) {
        String strValue = "12345";

        // Convert string to short using Short.parseShort()
        short shortValue = Short.parseShort(strValue);

        System.out.println("String value: " + strValue);
        System.out.println("Short value: " + shortValue);
    }
}

Output:

String value: 12345
Short value: 12345

Explanation:

• Short.parseShort(strValue) converts the string value to its short representation.

2. Using Short.valueOf()

The Short.valueOf() method returns a Short instance representing the specified string value. This method can also be used to convert a String to a short.

Example:

public class StringToShortUsingValueOf {
    public static void main(String[] args) {
        String strValue = "54321";

        // Convert string to short using Short.valueOf()
        short shortValue = Short.valueOf(strValue);

        System.out.println("String value: " + strValue);
        System.out.println("Short value: " + shortValue);
    }
}

Output:

String value: 54321
Short value: 54321

Explanation:

• Short.valueOf(strValue) converts the string value to its short representation.

3. Complete Example Program

Here is a complete program that demonstrates both methods discussed above to convert a String to a Short.

Example Code:

public class StringToShortExample {
    public static void main(String[] args) {
        String strValue1 = "12345";
        String strValue2 = "54321";

        // Using Short.parseShort() Method
        short shortValue1 = Short.parseShort(strValue1);
        System.out.println("Using Short.parseShort():");
        System.out.println("String value: " + strValue1 + " -> Short value: " + shortValue1);

        // Using Short.valueOf() Method
        short shortValue2 = Short.valueOf(strValue2);
        System.out.println("\nUsing Short.valueOf():");
        System.out.println("String value: " + strValue2 + " -> Short value: " + shortValue2);
    }
}

Output:

Using Short.parseShort():
String value: 12345 -> Short value: 12345

Using Short.valueOf():
String value: 54321 -> Short value: 54321

4. Conclusion

Converting a String to a Short in Java can be accomplished in several ways. The Short.parseShort() and Short.valueOf() methods are both straightforward and widely used. By understanding these different methods, you can choose the one that best fits your needs and coding style.

Happy coding!
