How to use System.out.println in Java

Question

could you help me resolve my problem ?

I wrote this simple Java program:

import java.util.Scanner; public class Something { public static void main(String args[]) { Scanner s = new Scanner(System.in); char c1,c2; c1=s.findWithinHorizon(".", 0).charAt(0); c2=s.findWithinHorizon(".", 0).charAt(0); System.out.println(c1); System.out.println(c2); s.close(); } }

When I press tf on my keyboard, the following prints on my console:

t r

What I am looking for is a single-line output, like

tr

instead of

t r

I tried System.out.println(c1, c2) but it is not working.

Thank you in advance.

@SouravSachdeva that wouldn't do what OP wants, because they are chars: it would promote them to ints and add them. — Andy Turner

You should use the print() method from the System static class. Here is the Oracle Java documentation considering the PrintStream class, which is accessed through the System.out call (out is a PrintStream there).

Here is a working sample:

public class Something { public static void main(String args[]) { Scanner s = new Scanner(System.in); char c1,c2; c1 = s.findWithinHorizon(".", 0).charAt(0); c2=s.findWithinHorizon(".", 0).charAt(0); System.out.print(c1); System.out.print(c2); s.close(); } }

Use System.out.print not System.out.println

If you have multiple characters and want to print them in a single line then use the following logic.

for (int i = 0; i < s.length(); i++) { System.out.print(s.charAt(i)); }

Use System.out.print(char c) instead of System.out.println(char c) the difference between print and println is that println introduce a break line at the end of each output. You also can do a concatenation System.out.println(char1+""+char2)

OP is printing chars, not Strings.

console gave me output 230

Try this System.out.println(char1+""+char2); It gave you that output because char also has a numeric representation called ASCII asciitable.com
