Use the equals method to compare strings in java.

i am also using this but the same problem :(

if(lblslctdop7.equals(lblcorrectans7)){
lblrightwrong7.setText("TRUE");
score++;
}
else{
lblrightwrong7.setText("FALSE");
}

...but keep in mind that using the comparison from UI strings to fork semantically different action would be the abuse of technology.
Separate data model, application logic and UI.

In Java you need to use .equals(..) to compare strings.

The code from your comment doesn't work because you're not checking the strings for equality but the labels.

This should work:

Java

if( lblslctdop1.getText().equals(lblcorrectans1.getText()) )
/* ... */
