Switch cases should remain small to keep the overall switch compact and readable.
The following code snippet illustrates this rule with the default threshold of 5:
switch (myVariable) { case 0: // Compliant - 5 lines till following case System.out.println(""); System.out.println(""); System.out.println(""); break; default: // Non-Compliant - 6 lines till switch end System.out.println(""); System.out.println(""); System.out.println(""); System.out.println(""); break; }
