if statement comparing strings in java android [duplicate]

Answer 1

In java, when using == on two objects, you're not actually comparing the strings themselves. You'll need to use .equals(String).

== actually compares the two object's references, not their values.

string1.equals(String target) compares the two strings based off of the actual characters in the strings.

See: http://www.leepoint.net/notes-java/data/expressions/22compareobjects.html

Answer 2

== operator check object reference are equal or not but equals() method check values are same or not

    if (name == cname) 
   {    
    cursor.close();
    db.close();
    return true;
  }

change with it

 if (name.equals(cname)){        
    cursor.close();
    db.close();
   return true;
}

Answer 3

When comparing objects in java that are not primitive data types (int, char, boolean, etc...), you have to use the method Object#equals(Object), which returns a boolean.

So, when you are comparing two Strings, you are actually checking if the two Objects are the same instance, instead of the actual value.

All you have to do is just change name == cname to name.equals(cname).
