This method takes one argument of type short as its parameter. This method returns a Short instance representing the specified short value.

Parameters: One parameter is required for this method.

s: a short value.

Returns: a Short instance representing s.

Exceptions: NA

Java

public class ShortvalueOf {
    public static void main(String[] args) {

        short s = 14;
        System.out.println(Short.valueOf(s));
    }
}

Output:

14

Approach 2: When the method takes one argument of type String.

NumberFormatException - If the String does not contain a parsable short.

Java

public class ShortvalueOf2 {
    public static void main(String[] args) {

        String s = "123";
        System.out.println(Short.valueOf(s));
    }
}

Output:

123

Approach 2.1: NumberFormatException 

Java

public class ShortvalueOf2 {
    public static void main(String[] args) {

        String s = "hello";
        System.out.println(Short.valueOf(s));
    }
}

Output:

Exception in thread "main" java.lang.NumberFormatException: For input string: "hello"
	at java.base/java.lang.NumberFormatException.forInputString(NumberFormatException.java:68)
	at java.base/java.lang.Integer.parseInt(Integer.java:652)
	at java.base/java.lang.Short.parseShort(Short.java:130)
	at java.base/java.lang.Short.valueOf(Short.java:186)
	at java.base/java.lang.Short.valueOf(Short.java:212)
	

Approach 3: When the method takes two arguments.

Syntax:

Short java.lang.Short.valueOf(String s, int radix) throws NumberFormatException

This method takes two arguments one of type String and the other of type int as its parameter. This method returns a Short object holding the value extracted from the specified String when parsed with the radix given by the second argument. The first argument is interpreted as representing a signed short in the radix specified by the second argument.

Parameters: Two parameters are required for this method.

s: the string to be parsed.

radix: the radix to be used in interpreting s.

Returns: a Short object holding the value represented by the string argument in the specified radix.

Throws:

NumberFormatException - If the String does not contain a parsable short.

Java

public class ShortvalueOf3 {
    public static void main(String[] args) {

        String s = "101";
        int radix = 2;
        System.out.println(Short.valueOf(s, radix));
    }
}

Output:

5

Approach 3.1: NumberFormatException 

Java

public class ShortvalueOf3 {
    public static void main(String[] args) {

        String s = "8891";
        int radix = 2;
        System.out.println(Short.valueOf(s, radix));
    }
}

Output:

Exception in thread "main" java.lang.NumberFormatException: For input string: "8891" under radix 2
	at java.base/java.lang.NumberFormatException.forInputString(NumberFormatException.java:68)
	at java.base/java.lang.Integer.parseInt(Integer.java:652)
	at java.base/java.lang.Short.parseShort(Short.java:130)
	at java.base/java.lang.Short.valueOf(Short.java:186)
