I have following code :
System.out.println(" | 1 2 3 4 5 6 7 8 9");
System.out.println("----------------------------");
S开发者_如何转开发ystem.out.println("");
I use println to create a new line. Is it possible to do the same using \n or \r? I tried to add \n to the second println statment and continue printing with the print method but \n does not create a new line.
any ideas?
String newLine = System.getProperty("line.separator");//This will retrieve line separator dependent on OS.
System.out.println("line 1" + newLine + "line2");
System.out.println("hello"+"\n"+"world");
Your best shot would be with
String.format("%n")
or
System.out.printf("%n");
It is supposed to print a newline character, depending on the current platform, so it's perfect for the console.
If you are printing to a file, then it depends.
It does create a new line. Try:
System.out.println("---\n###");
You should use the built in line separator. The advantage is that you don't have to concern what system you code is running on, it will just work.
Since Java 1.7
System.lineSeparator()
Pre Java 1.7
System.getProperty("line.separator")
You might try adding \r\n instead of just \n. Depending on your operating system and how you are viewing the output, it might matter.
\n
creates a new line in Java. Don't use spaces before or after \n
.
Example: printing It creates\na new line
outputs
It creates
a new line.
Since you are on Windows, instead of \n use \r\n (carriage return + line feed).
//Case1:
System.out.println(" 1 2 3 4 5 6 7 8 9" + "\n" + "----------------------------");
//Case2:
System.out.printf(" 1 2 3 4 5 6 7 8 9" + "\n" + "----------------------------");
//Case3:
System.out.print(" 1 2 3 4 5 6 7 8 9" + "\n" + "----------------------------");
"\n" this is the simple method to separate the continuous String
System.out.print(values[i] + " ");
//in one number be printed
