if(!textField_1.setText.equals("Hello"))

That's Java :)

you can use != and == to compare references and basic types (int, float ... )

In c++ we can overload the operator, but in java we have to use equals()

Don't you want to use method `getText()`? if textField_1 is Swing object then `setText()` and `getText()` are methods – Kuba Apr 16 '15 at 12:45
at the begging of my code i put the "Hello" value ( textField_1.setText("Nº OPERARIO"); ), and after that i wan't to compare it and i used if(textField_1.setText.equals("Nº OPERARIO")) but ir shows that error – marcss Apr 16 '15 at 12:48
use textField_1.getText().equals("asasasas") – Kuba Apr 16 '15 at 12:48

This is how the string comparision should be done.

if(textField_1.setText.equals("Hello")){

}

Update: I think you must use the get method to get the text, therefore I am expecting textField_1.getText() will give you the text to be compared.

You need to use getText() method to compare.

if(textField_1.getText() != ("Hello")){
//not matched
}else{
//matched
}

But it is better to use equals() method to compare.

if(!textField_1.getText().equals("Hello")){
//not matched
}else{
//matched
}

Note That: == tests for reference equality.

.equals() tests for value equality.
