[Solved] Java not equals with OR

by


To understand the difference, it always helps to read out your condition statement in english.

if ( !name.equals("abc") || !name.equals("cba") )

Translates to

If name does not equal “abc” OR name does not equal “cba”, then…

Whereas,

if ((!(name.equals("abc") || name.equals("cba") )))

If (name equals “abc’ OR name equals “cba” ) IS FALSE, then…

or, by Boolean Logic,

If name does not equal “abc” AND name does not equal “cba”, then…

The two are definitely not the same.
