什么是最简单的方法来生成一个字符串的n个重复的字符？ [英] What is the easiest way to generate a String of n repeated characters?

问题描述

给定一个字符c和数字n，如何创建一个由n个重复的c组成的字符串？手动操作太麻烦了：

Given a character c and a number n, how can I create a String that consists of n repetitions of c? Doing it manually is too cumbersome:

StringBuilder sb = new StringBuilder(n);
for (int i = 0; i < n; ++i)
{
    sb.append(c);
}
String result = sb.toString();

当然有一些静态库函数已经为我做了这件事？

Surely there is some static library function that already does this for me?

推荐答案

int n = 10;
char[] chars = new char[n];
Arrays.fill(chars, 'c');
String result = new String(chars);
