import java.util.List;

public class MyClass {
     private static String[] split_to_array(String s, int size) {
        List<String> parts = new ArrayList<>();
    
        int len = s.length();
        for (int i = 0; i < len; i += size) {
            parts.add(s.substring(i, Math.min(len, i + size)));
            //substring(int beginIndex, int endIndex)
        }
        return parts.toArray(new String[0]);
    }
    public static void main(String args[]) {
        String s = "java c c++ c# php python";

        String[] arr = split_to_array(s, 4);
