I do a Action on Middle ware and if its success i get the Value as 

```
String result = ["RESULT","DELETE","OK"]

```

And in Case if the Operation is Failed i get the resposne as 

```
String result = ["RESULT","DELETE","ERROR"]

```

I need to know if the Operation is success Or Fail so for this i have done this 

```
public class Test {

    public static void main(String args[]) {

        String result = "[\"RESULT\",\"DELETE\",\"ERROR\"]";

        if (!result.contains("ERROR")) {
            System.out.println("success");
        } else {
            System.out.println("Failed");
        }

    }

```

This is working fine , but not sure if this has any negative impact / or in cases the code may Fail .

Please suggest if there is a better approach .
