如何在Java中对齐下一行​​？

Question

I can't figure out how to right align these columns in JAVA. I tried several ways but none of them work. It works for other characters but not for Chinese.

String line1="冻结金额";
String line2="投资中金额";
String line3="投资中金额额";
String line4="投资中金中金额";
System.out.format("%-10s %s %n",line1, "XX" );
System.out.format("%-10s %s %n",line2, "XX" );
System.out.format("%-10s %s %n",line3, "XX" );
System.out.format("%-10s %s %n",line4, "XX" );

This is the expected result but even here it is not displayed correctly

冻结金额             XX 
投资中金额           XX
投资中金额额         XX
投资中金中金额       XX

Answer 1

You could (ab-)use the tai tou , full width space, "\　" :

System.out.println(String.format("%-10s %s",line1, "XX").replace(" ", "\u3000"));

Though with litte effort, you could do HTML output.

Answer 2

There is nothing wrong with the Java code, only the way the output is displayed.

The output is as follows:

冻结金额       XX 
投资中金额      XX 
投资中金额额     XX 
投资中金中金额    XX 

If you were actually to count the number of characters or do:

System.out.println(String.format("%-10s %s ",line1, "XX").length());
System.out.println(String.format("%-10s %s ",line2, "XX").length());
System.out.println(String.format("%-10s %s ",line3, "XX").length());
System.out.println(String.format("%-10s %s ",line4, "XX").length());

You'd see that each line has the same length (14).

The problem is that the display font doesn't show Chinese characters as the same size as other characters.

Answer 3

I use this method, however I have no idea how it will work with Chinese characters:

public String padRight(String s, int n) 
{
    return String.format("%1$-" + n + "s", s);  
}

Call it like so: padRight(StringToBePaddedToTheRight, intNumberOfPadsToTheRight);

Answer 4

Thanks Guys

You are right, nothing wrong with the code only the editor configuration.

In my case I am using eclipse editor, I just change the default font for an Unicode.

冻结金额　　　　　　　XX
投资中金额　　　　　　XX
投资中金额额　　　　　XX
