comparing string values

Question

I want to compare 2 strings. My first value is in 'list[0][0]' variable and the second value is in item[0]. But when I am comparing the 2 strings using 'if' statement, I don't get the answer.

if(selected_list[0][0]==items[0]) { // some code } it is not working. But when I am hard-coded these values, it is working fine. if("banana"=="banana") { // some code } Please give me the solution? Thank you..

Answer 1

Here is an explanation of how strings should be compared and the different options for doing so. They aren't as simple as comparing int's.

if (string1.equals(string2))

Answer 2

You have to compare it as [list[0][0] isEqualToString:items[0]] otherwise you are comparing their addresses not the values.

Answer 3

Use the compareTo() or equals() method of one of your strings, passing the other string as argument.

string1.equals(string2)
// returns true if both strings are equal

string1.compareTo(string2)
// returns 0 if both strings are equal
