How to Convert a String value to Short value in Java with Examples
Given a String “str” in Java, the task is to convert this string to short type.
Examples:
Input: str = "1"
Output: 1
Input: str = "3"
Output: 3
Approach 1: (Naive Method)
One method is to traverse the string and add the numbers one by one to the short type. This method is not an efficient approach.
Approach 2: (Using Short.parseShort() method)
The simplest way to do so is using parseShort() method of Short class in java.lang package. This method takes the string to be parsed and returns the short type from it. If not convertible, this method throws error.
Syntax:
Short.parseShort(str);
Below is the implementation of the above approach:
Example 1: To show successful conversion
class GFG {
public static short convertStringToShort(String str)
{
return Short.parseShort(str);
}
public static void main(String[] args)
{
String stringValue = "1" ;
short shortValue;
shortValue = convertStringToShort(stringValue);
System.out.println(
stringValue
+ " after converting into short = "
+ shortValue);
}
}
|
Output:
1 after converting into short = 1
Approach 3: (Using Short.valueOf() method)
The valueOf() method of Short class converts data from its internal form into human-readable form.
Syntax:
Short.valueOf(str);
Below is the implementation of the above approach:
Example 1: To show successful conversion
class GFG {
public static short convertStringToShort(String str)
{
return Short.valueOf(str);
}
public static void main(String[] args)
{
String stringValue = "1" ;
short shortValue;
shortValue = convertStringToShort(stringValue);
System.out.println(
stringValue
+ " after converting into short = "
+ shortValue);
}
}
|
Output:
1 after converting into short = 1
