Java中的 Matcher matches() 方法及示例

Matcher 类matches()方法用于获取此模式是否与此匹配器匹配的结果。它返回一个显示相同的布尔值。

句法:

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,显示此模式是否与此匹配器匹配。

下面的示例说明了 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
