if gender equals g1     lt --- if gender     Female     lt ---   You have semicolon after if REMOVE IT

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      In Java  one of the most common mistakes newcomers meet is using    to compare Strings  You have to remember     compares the object references  not the content

String unlike int or other numeric variables are compared in Java differently than other languages   To compare Strings in Java  android  it is used the method  compareTo     so the code should be like this   if gender compareTo  Male    0      salutation   Mr      if gender compareTo  Female    0      salutation   Ms

In Java we don t compare string as you are doing above    Here is String comparison         if  gender equalsIgnoreCase  Male              salutation    Mr          else if  gender equalsIgnoreCase  Female              salutation    Ms

The    operator checks to see if two objects are exactly the same object  Two strings may be different objects  but have the same value  have exactly the same characters in them   Use the  equals   method to compare strings for equality   http   www leepoint net notes-java data strings 12stringcomparison html

I think the above mentioned answer is correct Because    is for testing whether two strings are the same object whereas  equals   tests whether two strings have the same value

User · Answer

Your gender     Male  is actually comparing the object references for the object gender and a different object Male  What you have to use is the  equals   method to compare the value of the objects

Actually every code runs well here  but your probleme probably come from your gender variable  Did you try to do a simple System out println gender   before the comparaison
