Java Matcher matches()用法及代码示例

匹配器类的matches()方法用于获取结果，无论此模式是否与此匹配器匹配。它返回一个显示相同值的布尔值。

用法:

public boolean matches()

参数：此方法不带任何参数。

返回值：此方法返回一个布尔值，该值显示此模式是否与此匹配器匹配。

下面的示例说明Matcher.matches()方法：

示例1:

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

输出：

Result: false

示例2:

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

输出：

Result: false
