Java System out print formatting

Since you re using formatters for the rest of it  just use DecimalFormat   import java text DecimalFormat   DecimalFormat xFormat   new DecimalFormat  000   System out print xFormat format x   1            Alternative you could do whole job in whole line using printf   System out printf   03d  s   s     s     n    x   1     the payment number formatter format monthlyInterest       round our interest rate formatter format principleAmt   formatter format remainderAmt

Just use  t to space it   Example   System out println monthlyInterest     t      as far as the two 0 in front of it just use a if else statement  ex   x   x 1  if  x  lt  10       System out println  00   x     else if  x  lt  100       System out println  0   x     else      System out println x       There are other ways to do it  but this is the simplest

Since you are using Java  printf is available from version 1 5  You may use it like this  System out printf   03d    x    For Example   System out printf   03d    5   System out printf   03d    55   System out printf   03d    555     Will Give You  005 055 555  as output  See  System out printf and Format String Syntax

Something likes this  public void testPrintOut         int val1   8      String val2     951 23       String val3     215 92       String val4     198 301 22       System out println String format   03d  7s  7s  11s   val1  val2  val3  val4         val1   9      val2     950 19       val3     216 95       val4     198 084 26       System out println String format   03d  7s  7s  11s   val1  val2  val3  val4

Use System out format

Are you sure that you want  055  as opposed to  55   Some programs interpret a leading zero as meaning octal  so that it would read 055 as  decimal  45 instead of  decimal  55   That should just mean dropping the  0   zero-fill  flag      e g   change System out printf   03d    x   to the simpler System out printf   3d    x
