This Java code uses the String.format method to create a formatted string, specifically left-aligning the contents of s within a field of width n.

Components:

1. %-n:

   • The %- indicates left alignment (padding spaces to the right).
   • The n specifies the minimum width of the field.

2. s:

   • This is the input string to format.

Details:

• The method ensures the string s is padded with spaces to the right, so the total length of the resulting string is at least n characters wide.
• If s is already longer than n, no additional padding is applied, and s is returned as it is.

Example:

int n = 10;
String s = "Hello";
String result = String.format("%-" + n + "s", s);
System.out.println("'" + result + "'");

Output:

'Hello     '

Here:

• Hello is padded with spaces to ensure its total length is 10.
• The resulting string 'Hello ' has 5 spaces padding it on the right.

If s is longer than n (e.g., s = "HelloWorld123"):

• No padding is added, and the output is simply the original string ("HelloWorld123").
