How can I left-align strings using String.format()?

Question

I\'m using String.format() in Java trying to emulate the printf() control channel available in C. I understand how to specify that a string should be placed in a field which

Answer 1

System.out.format("%-10d%-32s%-16s%-16s%-32s", obj.getId(), obj.getBname(), obj.getAname(),obj.getLanguage(),obj.getPublication());

Just add hyphen - in front of the number.

Answer 2

Same way as with printf -- use a - modifier in the format

Answer 3

Like this?

class F { 
  public static void main( String ... args ) { 
    String [] status =  { "EXECUTING", "READY-SUSPENDED", "CREATED" };
    int [] pids =  {123, 34, 1231 };
    int i = 0;
    for( String s : status ) { 
       System.out.printf("Process PID: %5d Status : %s%n", pids[i++], s);
    }  
  }
}

Output:

$java F
Process PID:   123 Status : EXECUTING
Process PID:    34 Status : READY-SUSPENDED
Process PID:  1231 Status : CREATED
