public class AvoidNestedBlocksCheck
extends Check
public void guessTheOutput() { int whichIsWich = 0; { int whichIsWhich = 2; } System.out.println("value = " + whichIsWhich); }and debugging / refactoring leftovers such as
// if (someOldCondition) { System.out.println("unconditional"); }A case in a switch statement does not implicitly form a block. Thus to be able to introduce local variables that have case scope it is necessary to open a nested block. This is supported, set the allowInSwitchCase property to true and include all statements of the case in the block.
switch (a) { case 0: // Never OK, break outside block { x = 1; } break; case 1: // Never OK, statement outside block System.out.println("Hello"); { x = 2; break; } case 1: // OK if allowInSwitchCase is true { System.out.println("Hello"); x = 2; break; } }
