I'm using ms-dos to run my java program. I am working on listing a list of data as shown below:
ID      Name                  Age      Gender
---      ----------------------------------      -----      ------------
1001      John                  21      M
1023      Jass Lee   8  M

How do i align  Jass Lee's age and gender properly?

Try

      final String COLS = "%6s%16s%4s%7s\n";
      System.out.printf(COLS, "ID", "Name", "Age", "Gender");

This is what i am working on but i can't align the rows properly.

public void display(int tgt)
      {
            
            System.out.print(database[tgt].getID()+"   ");
            System.out.print(database[tgt].getName()+" ");
            System.out.print(database[tgt].getAge()+"  ");
            System.out.print(database[tgt].getGender()+"   ");
            System.out.print(database[tgt].getMobile()+" ");
            System.out.print(database[tgt].getCourseTitle()+" ");
            System.out.print(database[tgt].getFee()+"\n");
}

Adding " " will not do it - you need tab spaces, or better use printf () as CEHJ suggested

I am using j2sdk1.4.2_13 to compile and run the java files. Is this the reason why i can't run System.printf?
