It is because you are using System.out.println. It means that it goes to the next line, it works like if you add a line break at the final of the String. Change it for System.out.print to print all your code in a line.

这是因为您正在使用System.out.println。这意味着它会转到下一行，就像在String的最后添加换行符一样。将其更改为System.out.print以在一行中打印所有代码。

For example, using System.out.println:

例如，使用System.out.println：

Code

码

System.out.println("Hello");
System.out.println("World");

Output

产量

Hello
World

Now using System.out.print:

现在使用System.out.print：

Code

码

System.out.print("Hello");
System.out.print("World");

Output

产量

HelloWorld

Finally using System.out.print and String with \n:

最后使用System.out.print和String with \ n：

Code

码

String string = "Hello\nWorld";
System.out.print(string);

Output

产量

Hello
World

Look that using \n and System.out.println have the same behaviour.

看看使用\ n和System.out.println具有相同的行为。

You should use System.out.print instead of System.out.println. The last one appends a line break at the end of the argument. The line break character(s) is(are) the one(s) that make a new line appears on your output.

您应该使用System.out.print而不是System.out.println。最后一个在参数末尾添加换行符。换行符是在输出中出现新行的那一个。

Use StringBuilder to create a new "row" or System.out.print() to print to the same line

使用StringBuilder创建一个新的“行”或System.out.print（）以打印到同一行

Something like this:

像这样的东西：

 System.out.print("1st array : ");
for(int index=0; index
