Why 4: Normally you use a break; statement after a case: x = 1 --> case 1: x++ break; Jump out of the switch statement --> print 2 But without break; the code inside all cases (after the matched case) will be execute: x = 1 --> case 1, case 2, default x = 2 --> case 2, default x = 4 --> default

Result = 4 Run this program https://code.sololearn.com/cFrYPneSM16P/#java In switch break statement is missing.. When break is missing the flow continues to pass from all cases.
