Ideas for new refactorings from SonarQube

[JnRouvignac]

• Related "if/else if" statements should not have the same condition
• Identical expressions should not be used on both sides of a binary operator
• Unused method parameters should be removed
• Unused "private" fields should be removed
• Unused "private" methods should be removed

[Naxos84]

Removing of private fiels/methods can already be done through the "Save Actions" Preferences -> Java -> Editor -> Save Actions -> Configure -> Unnecessary Code
