将字符串拆分为字符串数组Java

Question

I have a String that looks like this

The#red#studio#502#4

I need to split it into 3 different Strings in the array to be

s[0] = "The red studio"
s[1] = "502"
s[2] = "4"

The problem is the first one should have only words and the second and third should have only numbers...

I was trying to play with the s.split() Method, but no luck.

Answer 1

String s= "The#red#studio#502#4";
String[] array = s.split("#(?=[0-9])");
for(String str : array)
{
  System.out.println(str.replace('#',' '));
}

Output:

The red studio  
502  
4

Answer 2

I've decided to edit out my impl because I think that @Srinivas's is more elegant. I'm leaving the rest of my answer though because the tests are still useful. It passes on @Srinivas's example too.

package com.sandbox;

import com.google.common.base.Joiner;
import org.apache.commons.lang.StringUtils;
import org.junit.Test;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Iterator;
import java.util.List;

import static org.junit.Assert.assertEquals;

public class SandboxTest {

    @Test
    public void testQuestionInput() {
        String[] s = makeResult("The#red#studio#502#4");
        assertEquals(s[0], "The red studio");
        assertEquals(s[1], "502");
        assertEquals(s[2], "4");
    }

    @Test
    public void testAdditionalRequirement() {
        String[] s = makeResult("The#red#studio#has#more#words#502#4");
        assertEquals(s[0], "The red studio has more words");
        assertEquals(s[1], "502");
        assertEquals(s[2], "4");
    }

    private String[] makeResult(String input) {
        // impl inside
    }
}

只需尝试：'String s [] = yourString.split（“＃”）'它将返回字符串数组....
