it even allows for short-circuiting the evaluation if an earlier Object.equal() call returns false (to be fair: commons / lang has an ObjectUtils.equals(obj1, obj2) method with identical semantics which could be used instead of EqualsBuilder to allow short-circuiting as ...

Add this method to theEmployeeclass, andEqualsTestwill start returning"true". So are we done? Not yet. Let’s test the above-modifiedEmployeeclass again in a different way. importjava.util.HashSet;importjava.util.Set;publicclassEqualsTest{publicstaticvoidmain(String[]args){Employeee1=newEmploye...
A similar methodString.equals()compares the strings in a case-sensitive manner. Never use'=='operator for checking the strings equality. It checks the object references, which is not desirable in most cases. 1.String.equalsIgnoreCase()API The syntax to use theequalsIgnoreCase()API is as follows...
