Java中的 CharsetDecoder malformedInputAction() 方法及示例
malformedInputAction ()方法是Java.nio.charset.CharsetDecoder 类的内置方法,该方法返回此解码器针对错误输入错误的当前操作。
语法:
public CodingErrorAction malformedInputAction()
参数:该函数不接受任何参数。
返回值:该函数返回此解码器对格式错误的输入错误的当前操作。
下面是上述函数的实现:
方案一:
// Java program to demonstrate
// the above function
import java.nio.charset.*;
import java.util.Iterator;
import java.util.Map;
public class GFG {
public static void main(String[] args)
{
// Gets the charset
Charset charset = Charset.forName("ISO-2022-CN");
// Get the CharsetDecoder
CharsetDecoder decoder = charset.newDecoder();
// Prints the CharsetDecoder
System.out.println("CharsetDecoder: " + decoder);
System.out.println("Current action for "
+ "malformed-input errors: "
+ decoder.malformedInputAction());
}
}
输出:
CharsetDecoder: sun.nio.cs.ext.ISO2022_CN$Decoder@232204a1
Current action for malformed-input errors: REPORT
方案二:
// Java program to demonstrate
// the above function
import java.nio.charset.*;
import java.util.Iterator;
import java.util.Map;
public class GFG {
public static void main(String[] args)
{
// Gets the charset
Charset charset = Charset.forName("x-windows-949");
// Get the CharsetDecoder
CharsetDecoder decoder = charset.newDecoder();
// Prints the CharsetDecoder
System.out.println("CharsetDecoder: " + decoder);
System.out.println("Current action for "
+ "malformed-input errors: "
+ decoder.malformedInputAction());
}
}
输出:
CharsetDecoder: sun.nio.cs.ext.DoubleByte$Decoder@232204a1
Current action for malformed-input errors: REPORT
