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
