Java Short decode()用法及代码示例

Java Short 类的 decode() 方法用于将字符串解码为 Short。它接受十进制、十六进制和八进制数。如果我们在字符串中放置其他内容，则此方法将抛出异常。

用法

public static Short decode(String x) throws NumberFormatException

参数

X：将被解码为 Short 的编码字符串。

异常

如果输入参数 "String x" 不包含可解析的 short 则它将抛出以下异常：throws NumberFormatException

返回值

decode() 方法将返回持有由 X 表示的短值的 Short 对象。

示例 1：(字符串输入中的十进制数)

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);  
}  
}

输出：

decoded String value in to Short  = 38

示例2：(字符串输入中的八进制数)

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);  
} 
}

输出：

decoded String value in to Short  = 8

示例 3：(字符串输入中的十六进制数)

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);  } }

输出：

decoded String value in to Short  = 15

例4：(输入错误，会抛出异常)

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);  }}

输出：

java.lang.NumberFormatException
