Java Snippet if and

[EvgeniyKvitnitskiy]

Hello all.
I’m try write some code in Java Snippet to have message popup at the end of execution. from my POV everything looks fine, but… even firs statement true - each time message show me second.

 if ( c_RTCQAStatus=="RL" &&   c_RTCISQUANTY == c_SAPUnrestricted && c_SAPLE==c_RTCISLE && c_RTCISLE=="A709")

//if (c_Status=="OK")
{
 
	JOptionPane.showMessageDialog
	(null,"Все ОК! " + "\n" +   "LE: RTCIS -" + c_RTCISLE + " , SAP-" + c_SAPLE +   "\n" + "RTCIS " + c_RTCQAStatus + " - " +  c_RTCISQUANTY +   "\n" + " SAP RL - " + c_SAPUnrestricted +   "\n" + " SAP QU - " + c_SAPInQualityInsp  +   "\n" + " SAP BL - " + c_SAPBlocked  , "Warning!", JOptionPane.INFORMATION_MESSAGE);
	}	
	else	
  {
	JOptionPane.showMessageDialog
		(null,"Что то пошло не так! " + "\n" +   "LE: RTCIS -" + c_RTCISLE + " , SAP-" + c_SAPLE +   "\n" + "RTCIS " + c_RTCQAStatus + " - " +  c_RTCISQUANTY +   "\n" + " SAP RL - " + c_SAPUnrestricted +   "\n" + " SAP QU - " + c_SAPInQualityInsp  +   "\n" + " SAP BL - " + c_SAPBlocked  , "Warning!", JOptionPane.ERROR_MESSAGE);
	}

The problem is the ==:

Issue with code in a java snippet?

Hi Claire, don’t compare Object types (e.g. Integer) with ==, but always go for the equals method instead (this is a Java fundamental, nothing KNIME specific): if (value1.equals(value2)) { … } The nasty thing is, sometimes == might still work, e.g. when you have values which are cached internally. So, this might explain that your workflow performed as expected under certain circumstances. Best, Philipp

Thank you very much, now it works as expected with equals
