'Print at a specific location in java output stream

 String s1= "SAM";
 int x=30;
 System.out.printf(s1); // prints at left most 
 s1=String.format("%03d",x);// formatting a number by 3 digits 
 System.out.printf("%15s",s1);//padding by 15 digits 
 System.out.println();

the task is to print the string and number in correct padding i.e whatever the length of string the number should start at 16th position. thanks in advance.

Solution 1:[1]

you can use the following template to achieve the result

    String Wrd = "SPKJ";
    int intVAlFor = 35;
    String Vn = "";
    
    if(Wrd.length()<= 15){
        Vn =  String.format("%0"+ (15 - Wrd.length() )+"d%s",0 ,Wrd);
        Vn = Vn + Integer.toString(intVAlFor);
    } else {
        Vn = Wrd.substring(0, 15);
        Vn = Vn + Integer.toString(intVAlFor);
    }
    
    System.out.println(Vn);

Output :

00000000000SPKJ35

You can change the formatting respective to formatting you want to use (Right Padding / Left Padding by making changes in String.format())

Solution 2:[2]

Your example is already padded by 13 spaces, so the number is at 16th position. So I thought you might want to padded by 15 in between of them. So the easiest is to use an empty string like following:

String s = "SAM";
int x = 30;
        
System.out.printf(s); //Prints at the most left
s = String.format("%03d", x); //Format the number by 3 digits 
System.out.printf("%15s%s", "", s); //Padded by 15 digits 
System.out.println();

SAM               030
