Hello, I have a series of codes that contain positive integers that I want to print making them occupy the same space.
For example given:
j1
j23
j777
I would like you to have zeros to the left and chains of the type to come out:
j0001
j0023
j0777
It should be noted that the j is static, I am interested in filling in the spaces between the numbers and the letters.
Try the following code:
//Letra a convertir
String letra = "j777";
//Se divide por la letra deseada "j"
String[] letras = letra.split("j");
//Se declara el formato al que se desea convertir
DecimalFormat format = new DecimalFormat("0000");
//Se aplica el formato a la segunda parte del arreglo y se concatena la 'j'
String letraFin = "j"+format.format(Integer.valueOf(letras[1]));
//Se imprime el resultado de la conversión
System.out.println("Formato final: "+ letraFin);
Console output:
Final format: j0777
