Hi Deepu,

Try this, this will work:
public class StringArrayTest {

    public static List<String> generateStringArray(Integer i){
        List<String> str=new List<String>();
        for(Integer j=0;j<i;j++){
            str.add('Test '+j);
        }
        return str;
    }
}

As your method should be static as it is given.

Let me know if you have any issue in that

You are not really doing anything in your generateStringArray() method. The proper way is to do something like this
 
public class StringArrayTest {
    
    public static List<String> generateStringArray(Integer n)
    {
        List<String> myArray = new List<String>();
        for(Integer i=0;i<n;i++)
        {
           myArray.add('Test '+i);
           System.debug(myArray[i]);
        }
        return myArray;
    }
}
