Developing a Command line utility in todays world will not help your
fathers business in any way!!!..
Go for a swing based utility...
newayz......
Dont use \t for indentation. just create a simple function that will
return the indented String by padding it with spaces..
Something like this :
String pad(String input, int num) {
StringBuilder prefix = new StringBuilder();
for(int i = 0;i<num;i++) {
prefix.append(" ");
}
prefix.append(input);
return prefix.toString();
}
Now you can use this method to pad your strings before printing..
outFile.println(pad("hello",16));
outFile.println(pad("hello",20));
