Java 中的 CharsetDecoder malformedingputaction()方法,带示例

原文:https://www . geeksforgeeks . org/charsetdecoder-malformedinputation-method-in-Java-with-examples/

malformedinputation()方法是Java . nio . charset . charset decoder 类的一个内置方法,该类返回该解码器针对格式错误的输入错误的当前操作。

语法 :

public CodingErrorAction malformedInputAction()

参数:该功能不接受任何参数。

返回值:该函数返回该解码器对格式错误输入错误的当前操作。

下面是上述功能的实现:

程序 1:

// 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

程序二:

// 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
