Splitting String into Array of Strings Java

提问by Andrey Chasovski

I have a String that looks like this

我有一个看起来像这样的字符串

The#red#studio#502#4

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

我需要在数组中将它分成 3 个不同的字符串

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...

问题是第一个应该只有单词，第二个和第三个应该只有数字......

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

我试图玩这个s.split()方法，但没有运气。

String[] array = s.split("#(?=[0-9])");
for(String str : array)

}

Output:

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.

我决定编辑我的 impl，因为我认为@Srinivas 的更优雅。不过，我将留下我的其余答案，因为这些测试仍然有用。它也传递了@Srinivas 的例子。

        assertEquals(s[1], "502");
        assertEquals(s[2], "4");

        String[] s = makeResult("The#red#studio#has#more#words#502#4");

        assertEquals(s[1], "502");
        assertEquals(s[2], "4");
    }

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

Simply try: 'String s[]= yourString.split("#")' it will return string array....

只需尝试： 'String s[]= yourString.split("#")' 它会返回字符串数组....
