The reason why global constants in Java use thestaticandfinalkeywords is becausefinalensures a variable cannot change, whilestaticensures only one copy of the constant variable is placed in memory, regardless of how many class instances are created. To new developers, the use of the keywordsstatic...

With all the changes that I mentioned in the previous sections, switch is the new cool kid on the block. It can also be used in use cases where only if-else could be used earlier. Also, developers realized that if/ if-else constructs have disadvantages too—the longif/elseconstructs are...
