Decode a string to short value

Short.decode(String nm) decodes a String into a Short. It accepts decimal, hexadecimal, and octal numbers given by the following grammar:

+/- 0x HexDigits 
+/- 0X HexDigits 
+/- # HexDigits 
+/- 0 OctalDigits

Small demo to illustrates the decode method.

public class Main {
  public static void main(String[] args) {
    /* j a  v  a 2s .co m*/
    System.out.println("Decimal 10:"+Short.decode("10"));
    System.out.println("Octal 10:"+Short.decode("010"));
    System.out.println("Hex F:"+Short.decode("0XF"));
    
    
    System.out.println("Negative Hex F:"+Short.decode("-0XF"));
  }
}

The output:

Convert string to a short value

Short class has the following methods we can use to convert a string to a short type value.

static short parseShort(String s) parses the string argument as a signed decimal short.
static short parseShort(String s, int radix) parses the string argument as a signed short in the radix specified by the second argument.
static Short valueOf(short s) returns a Short instance representing the specified short value.
static Short valueOf(String s) returns a Short object holding the value given by the specified String.
static Short valueOf(String s, int radix) returns a Short object holding the value extracted from the specified String when parsed with the radix given by the second argument.

The following code demonstrates the methods listed above.

public class Main {
  public static void main(String[] args) {
//from  ja v a 2s.  co m
    System.out.println(Short.parseShort("10"));
    System.out.println(Short.parseShort("10",8));
    
    System.out.println(Short.valueOf("10"));
    System.out.println(Short.valueOf("10",8));
    

  }
}
