I have some issues with printing my code. I want my result to be aligned neatly but it isn't like that. It would be very grateful if someone could help me with the issue.
my code is as follows :
public static void main(String[] args) {
for(int j=1 ; j<=31;j++) {
System.out.printf("%10d",j);
if(j%7==0) {
System.out.println();
}
}
}
the result I get to see on my screen as belows
Your code is correct. But you should use MONOSPACED (fixed width) font like Courier or Lucida Console in your terminal / console:
According to Formatting Numeric Print Output
Format specifiers begin with a percent sign (%) and end with a converter. The converter is a character indicating the type of argument to be formatted. In between the percent sign (%) and the converter you can have optional flags and specifiers
In this case:
% is format syntax mandatory prefix.- is the flag for Left-justified.10 means ten characters in width, with leading zeroes as necessary.d, A decimal integer.So your main method should be:
public class Tst {
public static void main (String[] args)
{
for(int j=1 ; j<=31;j++) {
System.out.printf("%-10d",j);
if(j%7==0) {
System.out.println();
}
}
}
}
Giving the resulting output:
