When I run the below code, I am getting ./Solution.java:13: error: incompatible types: Long cannot be converted to String error. I am not able to understand why.

public class Solution {
    public Long solve(Long A, int B) {
        String binaryStr = "";

        while(true) {
            if(A > 6) {
                binaryStr = String.valueOf((A % 2)) + binaryStr;
            } else {
                binaryStr = "0" + binaryStr;
            }
            
            A = Math.floor(Integer.parseInt(A) / 2);
            if(A == 0) {
                break;
            }
        }
        return binaryStr;
    } 
}

Somebody help me fix this problem.

Thanks in advance.
