The string %-15s%03d%n is a format string used with printf method in Java to specify how to format the output.
Let's break down each part:
%-15s: This specifies a placeholder for a string (s) that will be left-justified in a field of width 15 characters. The - sign indicates left-justification, and 15 specifies the width of the field. If the string is shorter than 15 characters, it will be padded with spaces to the right.
%03d: This specifies a placeholder for an integer (d) that will be formatted with leading zeros. The 0 indicates that leading zeros should be used for padding, and 3 specifies that the integer should be displayed with at least three digits. If the integer has fewer than three digits, leading zeros will be added to make it three digits long.
%n: This is a platform-independent newline character. It ensures that the next output starts on a new line.
So, when you use this format string with printf, it will format a string followed by an integer according to the specified format, ensuring that the string is left-justified in a 15-character field and the integer is expressed in exactly three digits with leading zeros if necessary, and then followed by a newline character.
