无法以“ \\ n”开始新行？

Question

I am working on a project and there is a small part of it really confusing me. Say I have a String array :

String[]text = {"string","array"}; 

for example.
And I want to make it to a single String with a new line "\\n" between every single word. So here is my code

public String setText(String [] text) throws UnsupportedEncodingException{
    StringBuffer result = new StringBuffer();
    String newline = System.getProperty("line.separator");
    if (text.length > 0) {
        result.append(text[0]);
        for (int i=1; i<text.length; i++) {
            result.append(newline);
            result.append(text[i]);
        }
    }
    return result.toString();
}

My code doesnt work. The return value is a single string but when I use it, it is still in one line.

Anyone can help me with this?

Thank you

Answer 1

Did you see what System.getProperty("line.separator"); returns? In different OS it will be different symbols \\n - Linux and \\r\\n in Windows Try to use System.getProperty("line.separator", "\\r\\n"); or System.getProperty("line.separator", "\\n");

Answer 2

Depends on how you use the result. Have you tried writing it to System.out / a file or anything similar?

Answer 3

我建议使用Google的Guava库中的 Joiner 。

Joiner.on(System.getProperty("line.separator")).join(text)
