Print multiple char variables in one line?
提问by Kaptain
So I was just wondering if there was a way to print out multiple charvariables in one line that does not add the Unicode together that a traditional print statement does.
所以我只是想知道是否有一种方法可以char在一行中打印出多个变量，而不像传统的打印语句那样将 Unicode 添加在一起。
For example:
例如：
char a ='A';
char b ='B';
char c ='C';
System.out.println(a+b+c); <--- This spits out an integer of the sum of the characters
采纳答案by Oliver Charlesworth
System.out.println(a+""+b+""+c);
or:
或者：
System.out.printf("%c%c%c\n", a, b, c);

The println()method you invoked is one that accepts an intargument.
println()您调用的方法是一种接受int参数的方法。
With variable of type charand a method that accepts int, the chars are widenedto ints. They are added up before being returned as an intresult.
使用类型的变量char和接受 的方法int，将chars扩展为ints。在作为int结果返回之前将它们相加。
You need to use the overloaded println()method that accepts a String. To achieve that you need to use Stringconcatenation. Use the +operator with a Stringand any other type, charin this case.
您需要使用println()接受 a的重载方法String。要实现这一点，您需要使用String串联。在这种情况下，将+运算符与 aString和任何其他类型char一起使用。
System.out.println(a + " " + b + " " + c); // or whatever format

System.out.print(a);System.out.print(b);System.out.print(c) //without space
System.out.print(a);System.out.print(b);System.out.print(c) //无空格

This will serve : System.out.println(String.valueOf(a) + String.valueOf(b) + String.valueOf(c));.
这将服务：System.out.println(String.valueOf(a) + String.valueOf(b) + String.valueOf(c));。

System.out.println(new StringBuilder(a).append(b).append(c).toString());

You can use one of the String constructors, to build a string from an array of chars.
您可以使用 String 构造函数之一从字符数组构建字符串。
System.out.println(new String(new char[]{a,b,c}));
