Hi find your solution in c++ : https://ideone.com/I1Ic1j
where I used find and replace functions from string and if you want to implement it in java,it will be easy to implement with this solution.

#include <iostream>
#include<string>
using namespace std;

// To execute C++, please define "int main()"
int main() {

   string str="Is it appropriate ans to your problem? : by queryhome",key="ho";
 // cin>>str>>key;
  size_t i = 0;
while (true) {
     i = str.find(key, i);
     if (i== std:: string ::npos) 
     {
        break;
     }
     str.replace(i, key.length(),"");
     i += 1;
}
  cout<<str<<endl;
  return 0;
}

without seeing your requirement, I wrote this in c++, if you  are not able to write solution in c/java then comment below
