How to align String on console output

Question

I\'ve to write code for:

Answer 1

You can use format() to format your output according to your need..

    for(int i=1; i<13; i++){
        for(int j=1; j<13; j++){

           System.out.format("%5d", i * j);
        }
        System.out.println();  // To move to the next line.
    }

Or, you can also use: -

System.out.print(String.format("%5d", i * j));

in place of System.out.format..

Here's is the explanation of how %5d works: -

• First, since we are printing integer, we should use %d which is format specifier for integers..
• 5 in %5d means the total width your output will take.. So, if your value is 5, it will be printed to cover 5 spaces like this: - ****5
• %5d is used to align right.. For aligning left, you can use %-5d. For a value 5, this will print your output as: - 5****
