Java Short parseShort()用法及代碼示例

Java Short 類的 parseShort() 方法用於將字符串參數解析為有符號十進製短整數。

用法

static short parseShort(String x)throws NumberFormatException

參數

x:包含要解析的短表示的字符串。字符串中的所有字符都必須是十進製數字。

返回值

它返回由十進製參數表示的短值。

異常

如果字符串不包含可解析的 short，則拋出 NumberFormatException。

例子1

public class ShortParseShortExample1 {

	public static void main(String[] args) {
                //with Positive String Value
	      String x = "100";
	      
	      // it returns signed decimal short value of string
	      short sValue = Short.parseShort(x); 
	  
	      // printing signed parseShort value
	      System.out.println("String "+x +" , parse value into parseShort  =" + sValue);  
	}
}

輸出：

String 100 , parse value into parseShort  =100

例子2

public class ShortParseShortExample2 {

	public static void main(String[] args) {
                //with Negative String Value
	      String x = "-500";
	      
	      // it returns signed decimal short value of string
	      short sValue = Short.parseShort(x); 
	  
	      // printing signed parseShort value
	      System.out.println("String "+x +" , parse value into parseShort  =" + sValue);  
	}
}

輸出：

String -500 , parse value into parseShort  =-500

例子3

public class ShortParseShortExample3 {

	public static void main(String[] args) {
		   
	      String x = "Hello";
	      
	      // in this case, it will throw exception  because String  doesn't contain parsable value.
	      short sValue = Short.parseShort(x); 
	  
	      // printing signed parseShort value
	      System.out.println("String "+x +" , parse value into parseShort  =" + sValue);  
	}
}

輸出：

NumberFormatException

Java Short parseShort(String x, int radix) 方法

java Short 類的 parseShort(String x, int radix ) 方法用於將字符串參數解析為第二個參數指定的基數中的有符號short。

用法

static short parseShort(String x, int radix)   throws NumberFormatException

參數

x:包含要解析的短的字符串。

radix:解析包含短值的字符串時要使用的基數。

返回值

它返回由指定基數中的字符串參數表示的 short。

異常

如果出現以下情況，它會拋出 NumberFormatException：

第一個參數為空或長度為零的字符串
字符串的任何字符都不是數字。
基數小於 Character.MIN_RADIX 或大於 Character.MAX_RADIX
字符串表示的值不是 short 類型的值

示例 4

public class ShortParseShortExample4 {

	public static void main(String[] args) {
		   
		  String x="100";
		  int radix=2;
	      // it parse string  as a signed short in the radix
	     short  shortValue = Short.parseShort(x,radix);
	      System.out.println(" String "+x+" parsed specified by radix  "+radix + "  , into signed decimal short = "+ shortValue);
	}
}

輸出：

String 100 parsed specified by radix  2  , into signed decimal short = 4

例 5

public class ShortParseShortExample5{

	public static void main(String[] args) {
		   
		  String x="abc"; //Non parsable  value. throw exception
		  int radix=2;
	      // it parse string  as a signed short in the radix
	     short  shortValue = Short.parseShort(x,radix);
	      System.out.println(" String "+x+" parsed specified by radix  "+radix + "  , into signed decimal short = "+ shortValue);
	}
}

輸出：

NumberFormatException

例 6

字符串長度為零

public class ShortParseShortExample6 {

	public static void main(String[] args) {
		   
		  String x=" "; //String length is Zero . throw exception
		  int radix=2;
	      // it parse string  as a signed short in the radix
	     short  shortValue = Short.parseShort(x,radix);
	      System.out.println(" String "+x+" parsed specified by radix  "+radix + "  , into signed decimal short = "+ shortValue);
	}
}

輸出：

NumberFormatException

例 7

public class ShortParseShortExample7 {

	public static void main(String[] args) {
		   

	      // it parse string  as a signed short in the radix
	     short  shortValue = Short.parseShort("55", 6);
	      System.out.println(" String  parsed specified by radix  , into signed decimal short = "+ shortValue);
	}
}

輸出：

String  parsed specified by radix  into signed decimal short = 35
