1. while the array is larger than the target number of variable:"searchFor" , it is no need to search for the result that is larger than the "search target", therefore, we should break the loop to save more resources.
2. the variable j in the statement of "System.out.println("i = " + j); " is not declare and initialize at the beginning, also, var j in the while loop does not match with the variable i which is the result we want to display. Therefore, this statement should correct to "System.out.println("i = " + i); " so as to display the result of each loop correctly.
