java正则hitend,Java Matcher hitEnd()用法及代码示例
Matcher類的hitEnd()方法用于檢查此匹配器上的模式匹配是否已停止。當在匹配器中找不到更多匹配的組時,匹配結束。此方法返回一個聲明相同的布爾值。
用法:
public boolean hitEnd()
參數:此方法不帶參數。
返回值:此方法返回一個布爾值,說明此匹配器是否已完成匹配。
下面的示例說明Matcher.hitEnd()方法:
示例1:
// Java code to illustrate hitEnd() 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 Geeks for For Geeks Geek";
// Create a matcher for the input String
Matcher matcher
= pattern.matcher(stringToBeMatched);
while (matcher.find()) {
System.out.println("Group matched: "
+ matcher.group());
// Check if the matching has ended
// using hitEnd() method
System.out.println("Has matching hit end: "
+ matcher.hitEnd());
}
// Check if the matching has ended
// using hitEnd() method
System.out.println("Has matching hit end: "
+ matcher.hitEnd());
}
}
輸出:
Group matched: Geeks
Has matching hit end: false
Group matched: Geeks
Has matching hit end: false
Group matched: Geeks
Has matching hit end: false
Group matched: Geeks
Has matching hit end: false
Has matching hit end: true
示例2:
// Java code to illustrate hitEnd() 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 FGF GFG GFG FGF";
// Create a matcher for the input String
Matcher matcher
= pattern.matcher(stringToBeMatched);
while (matcher.find()) {
System.out.println("Group matched: "
+ matcher.group());
// Check if the matching has ended
// using hitEnd() method
System.out.println("Has matching hit end: "
+ matcher.hitEnd());
}
// Check if the matching has ended
// using hitEnd() method
System.out.println("Has matching hit end: "
+ matcher.hitEnd());
}
}
輸出:
Group matched: GFG
Has matching hit end: false
Group matched: GFG
Has matching hit end: false
Group matched: GFG
Has matching hit end: false
Group matched: GFG
Has matching hit end: false
Group matched: GFG
Has matching hit end: false
Group matched: GFG
Has matching hit end: false
Group matched: GFG
Has matching hit end: false
Has matching hit end: true
