Just copy StringMerger.java file to your project
Example:
// define layers
ArrayList<StringMerger.Layer> layers = new ArrayList<>();
layers.add(new StringMerger.Layer("left", 4, "Abcdefghijklmnopqrstuvwxyz"));
layers.add(new StringMerger.Layer("left", 0, "6789"));
layers.add(new StringMerger.Layer("right", 0, "@Rp20.000"));
layers.add(new StringMerger.Layer("right", 9, "HELLO"));
StringMerger merger = new StringMerger(30, ' ', layers);
// config
//merger.setMaxLength(30);
//merger.setBgChar(' ');
//merger.setLayers(layers);
String result = merger.getMergedString();
System.out.println(result); // output: "[email protected]"Concept:
Bg Char: " " ---> initial 30
Layer 1: " Abcdefghijklmnopqrstuvwxyz" ---> left 4
Layer 2: "6789 " ---> left 0
Layer 3: " @Rp20.000" ---> right 0 ---> "rstuvwxyz" will be replaced
Layer 4: " HELLO " ---> right 9 ---> "mnopq" will be replaced
Result : "[email protected]"
