Comparing two values in java that fetched from MSSQL

Hi i'm new to talend tool. While practicing i came through this. Its one of our previous project. I know how to compare two rows using NOT EQUAL in java, but this looks pretty different..

For example Comparison of two strings in java

 (!row1.nts_vcr.equals(row2.nts_vcr))

and comparison of two integer in java

(row1.SOC!=row2.SOC)  

I dunno what the below statement means

(!(row1.cntnr_id==row2.cntnr_id ))||  
 (!(row1.cntnr_sz_id==row2.cntnr_sz_id))||  
 (!(row1.cntnr_typ_id==row2.cntnr_typ_id))||  
 (!(row1.cntnr_stts_id==row2.cntnr_stts_id))
