Learn to repeat a given string N times, to produce a new string which contains all the repetitions, though a simple Java program. We will use methodSting.repeat(N)(sinceJava 11) and using regular expression which can be used tillJava 10. 1. String.repeat() API [Since Java 11] This m...
In this post, we are going to repeat a string N time using Java code. While working with string there can be a need of repeating a string, for that purpose, Java provides repeat() method in String class.The repeat() method is added in the String class from Java 11 version.There are...
如下所示: /** * 判断字符串是否包含重复字符 * @param str * @return */ public static boolean containRepeatChar(String str){ if(str==null||str.isEmpty()){ return false; } char[] elements=str.toCharArray(); for(char e:elements){ if(str.indexOf(e)!=str.lastIndexOf(e)){ re String...
2. repeat方法的实现 虽然Java 11引入了String.repeat(int count)方法,使得字符串重复的功能变得简单,但在早期版本的Java中,我们需要自行实现这一功能。 2.1 自定义重复方法的实现 可以使用循环来构建一个自定义的字符串重复方法。以下是一个示例: publicclassStringRepeater{publicstaticStringrepeat(Stringstr,intcount...
Java 11 – String.repeat()介绍 通过简单的Java程序,学习重复给定字符串N次,以产生包含所有重复的新字符串。我们将使用方法Sting.repeat(N)(因为Java 11)并使用常规方法该表达式可用于Java 10。 String.repeat() 此方法返回一个字符串,该字符串的值是给定字符串的重复count次的串联。如果字符串为空或count为零...
发现Java 21的StringBuilder和StringBuffer中多了repeat方法: /** *@throwsIllegalArgumentException {@inheritDoc} * *@since21 */@OverridepublicStringBuilderrepeat(intcodePoint,intcount){super.repeat(codePoint, count);returnthis; }/** *@throwsIllegalArgumentException {@inheritDoc} ...
在Java 8中,引入了repeat()方法,使得重复字符串变得更加简单和高效。这个方法接收一个整数参数n,表示要重复的次数。它会返回一个包含重复字符串的新String对象。例如,我们可以使用repeat()方法来重复一个字符串: ``` String repeatString = "Hello ".repeat(5); ``` 这样就可以将字符串"Hello "重复5次,并将...
