Java: Making System.out.println() argument span multiple lines?

Question

I have the following message:

System.out.println("Players take turns marking a square. Only squares not already marked can be picked. Once a player has marked three squares in a row, he or she wins! If all squares are marked and no three squares are the same, a tied game is declared. Have Fun!");

This is a very long message and streaks across my screen, I want to break it up into segments so it does not break the design flow of my code. When I press enter though, Java no longer interprets the line as a string; Java believes it is a separate statement. How can I make Java interpret multiline print statements?

Answer 1

Are you looking for something like this?

String line = "Information and stuff" + 
          "More information and stuff " + 
          "Even more information and stuff";

System.out.println(line);

Answer 2

Following Java's coding conventions:

System.out.println("Players take turns marking a square. "
                   + "Only squares not already marked can be picked. "
                   + "Once a player has marked three squares in a row, "
                   + "he or she wins! If all squares are marked and no "
                   + "three squares are the same, a tied game is declared. "
                   + "Have Fun!");

Always break with the concatenation operator to start the next line for readability.

Answer 3

在你想要换行的地方添加 '\\n'。

Answer 4

你可以输入： System.out.println("这是第一行\\n" + "这是第二行")

Answer 5

System.out.println("Players take turns marking a square."
+ "\nOnly squares not already marked can be picked."
+ "\nOnce a player has marked three squares in a row, he or she wins!"
+ "\nIf all squares are marked and no three squares are the same, a tied game is declared."
+ "\nHave Fun!");

Done.
