Is there any way I can print String array without using for loop?
提问by priyank
Is there any function in java like toString() to print a String array?
java中有没有像 toString() 这样的函数来打印字符串数组？
This is a silly question but I want to know if there is any other way than writing a for loop.
这是一个愚蠢的问题，但我想知道除了编写 for 循环之外是否还有其他方法。
Thanks.
谢谢。

String[] array = { "a", "b", "c" };
System.out.println(Arrays.toString(array));

String[] values= { ... }
System.out.println(Arrays.asList(values));

There is the Arrays.toString()method, which will convert an array to a string representation of its contents. Then you can pass that string to System.out.printlnor whatever you're using to print it.
有一个Arrays.toString()方法，它将一个数组转换为其内容的字符串表示。然后你可以将该字符串传递给System.out.println或任何你用来打印它的东西。

I think you are looking for
我想你正在寻找
System.out.printf(String fmtString, Object ... args)
Where you specify the format of the output using some custom java markup (this is the only part you need to learn). The second parameter is the object, in your case, the array of strings.
您可以在其中使用一些自定义 java 标记指定输出格式（这是您需要学习的唯一部分）。第二个参数是对象，在您的情况下，是字符串数组。

If you need a bit more control over the string representation, Google Collections Joinerto the rescue!
如果您需要对字符串表示有更多的控制，Google Collections Joiner可以帮助您！
String[] myArray = new String[] {"a", "b", "c"};
String joined = Joiner.on(" + ").join(myArray);
// => "a + b + c"
