String are immutable in Java. You can't change them. You need to create a new string with the character replaced. String myName = "domanokz"; String newName= myName.substring(0,4)+'x'+myName.substring(5); or you can use a StringBuilder: StringBuilder myName =newStringBuilder("domanok...
int cursor = 0; StringBuilder result = new StringBuilder(); while (cursor < replacement.length()) { char nextChar = replacement.charAt(cursor); if (nextChar == '\\') { cursor++; if (cursor == replacement.length()) throw new IllegalArgumentException( "character to be escaped is missing"...

Java解法 参考 题目描述 请实现一个函数,把字符串 s 中的每个空格替换成"%20"。 示例1: 输入:s = “We are happy.” 输出:“We%20are%20happy.” 限制: 0 <= s 的长度 <= 10000 方法一、遍历添加 在Python 和 Java 等语言中,字符串都被设计成「不可变」的类型,即无法直接修改字符串的某一位字符...
我上面的代码在复杂度上并没有太多优化,就是初始的考虑了怎么实现,现在来分析一下替换字符串的思路。 首先字符串是一个字符数组构成的,也就是char[],以字符串“We are happy.”为例,结构如下图: 字符串带上空格有13个字符,空格的char为32,如果要将空格字符替换成%20就肯定需要增加char数组长度,一个字符变成...
