Compare Result Set Values In Java. In this tutorial we will explore several functions introduced for the Comparator interface in Java 8. Java 8 lambdas can be leveraged effectively with the Comparator interface as well.
In my java code i have two resultsets rs1 and rs2 obtained as follows. The result set should get anywhere near the user interface. The ResultSet object has a cursorpointer which points to the current row.
When two or more objects are created without new keyword then both object refer same value.
Rs1 is result set. If you are willing to invest time in a custom set implementation there is an approach that can improve the almost the same case. For example Mapequals doesnt work when the value type is array as an arrays equals method compares identity and not the contents of the array. String is immutable in java.
