Java Short decode()用法及代碼示例

Java Short 類的 decode() 方法用於將字符串解碼為 Short。它接受十進製、十六進製和八進製數。如果我們在字符串中放置其他內容，則此方法將拋出異常。

用法

public static Short decode(String x) throws NumberFormatException

參數

X：將被解碼為 Short 的編碼字符串。

異常

如果輸入參數 "String x" 不包含可解析的 short 則它將拋出以下異常：throws NumberFormatException

返回值

decode() 方法將返回持有由 X 表示的短值的 Short 對象。

示例 1：(字符串輸入中的十進製數)

public class ShortDecodeExample1 { 
public static void main(String[] args) {      //String value   
String decimalValue = "38"; //Decimal number system   //String Value decoding into Short   
Short dec = Short.decode(decimalValue);   
System.out.println("decoded String value in to Short  = " + dec);  
}  
}

輸出：

decoded String value in to Short  = 38

示例2：(字符串輸入中的八進製數)

public class ShortDecodeExample2 { 
public static void main(String[] args) {   //Octal number system to write 5   
String decimalValue = "008";    //String Value decoding into Short   
Short dec = Short.decode(decimalValue);   
System.out.println("decoded String value in to Short  = " + dec);  
} 
}

輸出：

decoded String value in to Short  = 8

示例 3：(字符串輸入中的十六進製數)

public class DecodeExample3 { 
public static void main(String[] args) {   //Hexa number system to write 15   
String decimalValue = "0x0F";    //String Value decoding into Short   
Short dec = Short.decode(decimalValue);   
System.out.println("decoded String value in to Short  = " + dec);  } }

輸出：

decoded String value in to Short  = 15

例4：(輸入錯誤，會拋出異常)

public class DecodeExample4{ 
public static void main(String[] args) {   //Wrong input, it will throw Exception   
String decimalValue = "hello";    //String Value decoding into Short   
Short dec = Short.decode(decimalValue);   
System.out.println("decoded String value in to Short  = " + dec);  }}

輸出：

java.lang.NumberFormatException
