Brand new to Java student

I am taking a course and we are using Java as our language. I haven't
used Java before so I am VERY new.
I have an application that I am writing that gets a string from user
input (called type). If the value of the string is "C" then I am
simply trying to recognize that so that I can make 'decisions'.
For some reason I cannot figure out how to tell what the 'value' of
the string is, although I can use the string. Here is my code:
<code>
public void actionPerformed(ActionEvent e)
{
if(e.getSource() == submit)
{
startTemp = Double.valueOf(inField.getText()).doubleValue();
String type = new String();
type= inType.getText().toUpperCase().trim();
display.append(type);
if(type == "C" || type == "c")
{
display.append("Celsius");
}
}
}
</code>
the line: display.append(type);
works. It adds what ever is typed into the box to the text area. the
code in the if statement never executes.
I figure what ever I am doing wrong is probably stupid simple... but I
have never used Java so I don't see it. (Note I started with a case
statement only to find that you cannot do that with strings...)
Thanks for your help.
