I'm unable to compare two strings using the following code:

I have a string named "gender" which will have "Male" or "Female" as its value.

if(gender == "Male")
   salutation ="Mr.";
if(gender == "Female")
   salutation ="Ms.";

This didn't work, so I tried the following:

String g1="Male";
String g2="Female";
if(gender.equals(g1))
   salutation ="Mr.";
if(gender.equals(g2))
   salutation ="Ms.";

Again, it didn't work. Can someone please tell me how to compare string values using the if statement.

Try this

if(gender.equals("Male"))
 salutation ="Mr.";
if(gender.equals("Female"))
 salutation ="Ms.";

Also remove ;(semi-colon ) in your if statement

if(gender.equals(g1));
