In Java, converting a String to a Short is a common operation when dealing with numeric values provided as strings. A Short is a 16-bit signed integer, which means it can hold values from -32,768 to 32,767.
In this blog post, we will explore different methods to convert a String to a Short and provide practical examples with output to illustrate each approach.
Method 1: Using Short.parseShort() Method
The Short.parseShort() method is a simple way to convert a String to a Short. It parses the string argument as a signed short and returns the resulting numeric value.
public class StringToShortExample {
public static void main(String[] args) {
String strNumber = "12345";
try {
// Convert String to Short using parseShort()
short shortValue = Short.parseShort(strNumber);
System.out.println("Input String: " + strNumber);
System.out.println("Short Value: " + shortValue);
} catch (NumberFormatException e) {
System.out.println("Error: Invalid input for short conversion");
}
}
}
Output:
Input String: 12345
Short Value: 12345
Method 2: Using Short.valueOf() Method
The Short.valueOf() method converts a String to a Short object. It returns a Short instance representing the specified short value if the String is a valid representation of a short.
public class StringToShortExample {
public static void main(String[] args) {
String strNumber = "9876";
try {
// Convert String to Short using valueOf()
Short shortValue = Short.valueOf(strNumber);
System.out.println("Input String: " + strNumber);
System.out.println("Short Value: " + shortValue);
} catch (NumberFormatException e) {
System.out.println("Error: Invalid input for short conversion");
}
}
}
Output:
Input String: 9876
Short Value: 9876
Method 3: Using NumberFormat.parse() Method
You can also use NumberFormat to parse the String and convert it to a Short.
import java.text.NumberFormat;
import java.text.ParseException;
public class StringToShortExample {
public static void main(String[] args) {
String strNumber = "567";
// Convert String to Short using NumberFormat
try {
NumberFormat numberFormat = NumberFormat.getInstance();
short shortValue = numberFormat.parse(strNumber).shortValue();
System.out.println("Input String: " + strNumber);
System.out.println("Short Value: " + shortValue);
} catch (ParseException e) {
System.out.println("Error: Invalid input for short conversion");
}
}
}
Output:
Input String: 567
Short Value: 567
Method 4: Using Scanner class
The Scanner class can also be used to convert a String to a Short.
import java.util.Scanner;
public class StringToShortExample {
public static void main(String[] args) {
String strNumber = "32767";
// Convert String to Short using Scanner
try {
Scanner scanner = new Scanner(strNumber);
short shortValue = scanner.nextShort();
System.out.println("Input String: " + strNumber);
System.out.println("Short Value: " + shortValue);
} catch (NumberFormatException e) {
System.out.println("Error: Invalid input for short conversion");
}
}
}
Output:
Input String: 32767
Short Value: 32767
Conclusion
Converting a String to a Short is a frequent requirement in Java programming. You can achieve this using methods like Short.parseShort(), Short.valueOf(), NumberFormat, or Scanner. In this blog post, we provided practical examples with outputs to demonstrate each method's effectiveness. Always ensure proper error handling to handle invalid input gracefully and avoid potential exceptions.
