 *  Difference between the printf and format methods in Java
 *  printf() and format()both methods are used to format String in Java and more or less similar. printf()is more close to C programming language because of identical name used in  C programming language, Anyone who has work in C previously can easily start with this printf() method also its look more as a replacement of System.out.println(). if you don't want to print just want a formatted string for any other purpose String format() method is a way to go. In summary you can say that printf()writes on stdout while format() return you a formatted string.
