怎么得到新的字符串

Question

比如以前是String str = 12313.jsp,534.jsp,7556.jsp;
要删除534.jsp
得到新的字符串12313.jsp,7556.jsp
哪位知道怎么写啊

Answer 1

字符串大概就是 xxx.xxx,yyy.yyy,zzz.zzz这种形式?

Answer 2

写个死的                 String str = "12313.jsp,534.jsp,7556.jsp";
String s=str.substring(0,str.indexOf(","));
String spare1=str.substring(str.indexOf(",")+1);
String s2=spare1.substring(spare1.indexOf(","));
String s3=s+s2;
System.out.println(s3);

Answer 3

要是活动的话 接以“，”号切分字符串用map装起来在删除你想删除的

Answer 4

String str = "12313.jsp,534.jsp,7556.jsp";
System.out.println(str.replaceAll("(?<=,).*,(?!,)",""));

Answer 5

说说规律？每次会出现多少个以“，”分隔的内容？每次删除几个？package com.xuz.csdn.worldcup.day13;public class StringSplitTest { /**
 * @param args
 */
public static void main(String[] args) {
System.out.println(splitByCount("1.jsp,2.jsp,3.jsp",",",2));
System.out.println(splitByCount("1.jsp,2.jsp,3.jsp",",",2,3));
} private static String splitByCount(String str,String regex,int...nums){
StringBuffer sb = new StringBuffer();

String[] array = str.split(regex);
for (int i = 0; i < array.length; i++) {
if (isContains(nums, i+1) == false) {
sb.append(array[i]+",");
}
}

String temp = sb.toString();

return temp.substring(0,temp.length()-1);
}

private static boolean isContains(int[] sour,int i){
for (int j = 0; j < sour.length; j++) {
if (sour[j] == i) {
return true;
}
}

return false;
}
}

Answer 6

private static boolean isContains(int[] sour,int i){
        for (int j = 0; j < sour.length; j++) {
            if (sour[j] == i) {
                return true;
            }
        }
        
        return false;
    }
int[] -> List 然后用contains方法亦可。

Answer 7

 string str = "12313.jsp,534.jsp,7556.jsp";
       string[] s= str.Split(',');
        string ss="";
       if (str.Contains("534.jsp"))
       {
           for (int i = 0; i < s.Length; i++)
           {
               if (s[i] != "534.jsp")
               {
                   if (i != s.Length - 1)
                   {
                     ss+=s[i]+",";
                   }
                   else
                   {
                       ss += s[i];
                   }
               }
           }
       }

package com;import java.util.regex.Matcher;
import java.util.regex.Pattern;public class Test {
public static void main(String[] args) {
String str = "12313.jsp,534.jsp,7556.jsp";
Matcher matcher = Pattern.compile("(\\S{10})\\S{8}(\\S+)").matcher(str);
while (matcher.find()) {
System.out.println(matcher.group(1) + matcher.group(2));
}
}}

Answer 9

public static void main(String[] args) {
// 方法1:根据完整名字删除
String str = "12313.jsp,534.jsp,7556.jsp";
String delStr = "534.jsp";
str = str.replaceAll(delStr + ",", "");// 12313.jsp,7556.jsp
System.out.println(str);

// 方法2:根据模糊字段删除
String str2 = "12313.jsp,534.jsp,7556.jsp";
String delStr2 = "4.js";
str2 = str2.replaceAll(",?\\w*"+delStr2+"\\w*\\.?\\w*,?", ","); // 12313.jsp,7556.jsp
System.out.println(str2);
}

Answer 10

str.split(",");循环数组，删除下标为1的数据

Answer 11

    public static void main(String args[]){
     System.out.println(DeleteWord.delete("1.jsp,2.jsp,3.jsp,3.jsp,3.jsp,777.jsp,3.jsp", "3.jsp"));
    
    }
    public static String delete(String orginal,String target){
     StringBuffer result =new StringBuffer();
     String array[]=orginal.split(",");
     for(int i = 0;i<array.length;i++){
     if(!array[i].equals(target)){
     result.append(array[i]);
     result.append(",");
     }
     }
     return result.toString();
    }
