Java Matcher quoteReplacement(String)用法及代码示例

Matcher类的quoteReplacement(String string)方法用于获取作为参数传递的String的替换String文字。此String文字充当replace方法的参数。因此，quoteReplacement()方法充当替换方法的中间方法。

用法:

public static String quoteReplacement(String string)

参数：此方法采用参数字符串，该字符串是Matcher中要替换的String。

返回值：此方法返回一个字符串文字，它是匹配器的替换字符串。

下面的示例说明Matcher.quoteReplacement()方法：

示例1:

// Java code to illustrate quoteReplacement() method 
  
import java.util.regex.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // Get the regex to be checked 
        String regex = "Geek"; 
  
        // Create a pattern from regex 
        Pattern pattern = Pattern.compile(regex); 
  
        // Get the String to be matched 
        String 
            stringToBeMatched 
            = "GeeksForGeeks Geeks for For Geeks Geek"; 
  
        // Create a matcher for the input String 
        Matcher matcher 
            = pattern 
                  .matcher(stringToBeMatched); 
  
        // Get the String to be replaced 
        String stringToBeReplaced = "Geeks"; 
  
        // Get the String literal 
        // using quoteReplacement() method 
        System.out.println( 
            matcher 
                .quoteReplacement(stringToBeReplaced)); 
    } 
}

输出：

Geeks

示例2:

// Java code to illustrate quoteReplacement() method 
  
import java.util.regex.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // Get the regex to be checked 
        String regex = "FGF"; 
  
        // Create a pattern from regex 
        Pattern pattern 
            = Pattern.compile(regex); 
  
        // Get the String to be matched 
        String 
            stringToBeMatched 
            = "GFGFGFGFGFGFGFGFGFG FGF GFG GFG FGF"; 
  
        // Create a matcher for the input String 
        Matcher matcher 
            = pattern.matcher(stringToBeMatched); 
  
        // Get the String to be replaced 
        String stringToBeReplaced = "GFG"; 
  
        // Get the String literal 
        // using quoteReplacement() method 
        System.out.println( 
            matcher 
                .quoteReplacement(stringToBeReplaced)); 
  
        System.out.println( 
            matcher 
                .replaceAll( 
                    matcher 
                        .quoteReplacement( 
                            stringToBeReplaced))); 
    } 
}

输出：

GFG
GGFGGGFGGGFGGGFGGFG GFG GFG GFG GFG
