三种java 去掉字符串中的重复字符函数 public static void main(string[] args) { system.out.println(removerepeatedchar("ddddccffgd")); } public static string removerepeatedchar(string s) { if (s == null) return s; stringbuilder sb = new stringbuilder(); , len = s.
Java判断一个字符串str中中文的个数,经过总结,有以下几种方法(全部经过验证),可根据其原理判断在何种情况下使用哪个方法: 1. char[] c = str.toCharArray(); for(int i = 0; i < c.length; i ++) { String len = Integer.toBinaryString(c[i]); if(len.length() > 8) count ++; } 根据一个中文占两个字节,假如一个字符的字节数大于8,则判断为中文. 2 . S
public class EmployeeDemo { //方法一: public int search(String str,String strRes) {//查找字符串里与指定字符串相同的个数 int n=0;//计数器 // for(int i = 0;i<str.length();i++) { // // } while(str.indexOf(strRes)!=-1) { int i = str.indexOf(strRes); n++; str = str.substring(i+
