title: If statement does equalsIgnoreCase while not prefered
body: <p>If I use this code:</p>
  
  <pre><code>if(new File(inputNickname + ".acc").exists() == false) {
      System.out.println("[Login] This account does not exists!");
      exists = false;
  }
  </code></pre>
  
  <p>and I would make a text file called <code>example.acc</code>,
  it will say <code>true</code> if <code>inputNickname = "EXAMPLE"</code> or <code>"ExAmPle"</code>, etc.
  But I only want that <code>exists = true</code>, when <code>inputNickname</code> is <code>"example"</code> and not <code>"EXAMPLE"</code> or <code>"ExAmPlE"</code> etc.</p>
