如何在Java中将整个句子拆分为字符？

Question

I need to split:- "Hello World" into the following:

H

e

l

l

o

W

o

r

l

d

I have tried using .split(""). But after the space it is not working. How to split both strings?

Answer 1

Use StringName.toCharArray()

hope this might help you.

Answer 2

If you don't want the spaces, remove them before you split. And don't use split to get characters, better to get a character array directly:

s.replaceAll(" ", "").toCharArray()

If you don't even need a character array and you just want to print, then it's better to use streaming with a filter:

s.chars().filter(c -> c != ' ').forEach(c -> System.out.println((char)c))

Answer 3

Try this. Hope it works:

    String str = "Hello World";
    char [] ch = str.toCharArray();

    for( int i = 0; i < ch.length; i++ ) {
        if( ch[i] != ' ' ) { 
            System.out.println( ch[i] );
       }
    }

Answer 4

You can use String.toCharArry to convert a string into an array of characters:

String str = "Hello World";
char[] charArray = str.toCharArray();

Answer 5

If you want chars without space you can do the following

"Hello world".chars()
            .filter(e -> e != ' ')
            .forEach(e -> System.out.println((char)e));
