Answer 1

import java.util.Arrays;

public class Program
{
public static void main(String[] args) {

int a[] = {1, 2, 3, 4, 5, 6};

String star = Arrays.toString(a).replaceAll("\\[|\\]|,|\\s", "").replace("2", "").replace("", ",");

System.out.println(star);
//System.out.println(newStar);
// System.out.println(newStarNew);

// combining as stream
star = Arrays.toString(a).replaceAll("\\[|\\]|,|\\s2","").replace(" ", ",");

System.out.println(star);

// single substring regex..

star = Arrays.toString(a).replaceAll("\\[|\\]|\\s|2,","");
System.out.println(star);

}
}

// 1,3,4,5,6 is what you trying I think..
