Why do we not enclose the content that is executed after a condition in an if statement, like below?
switch (item.getItemId()) { case R.id.nextImage: imageIndex ++; if (imageIndex >= imageResIds.length) { image = 0; } loadimage(); break; }

9,835 PointsIt's just how the Java compiler works. For single line of code after an if/for/while statement, it doesn't need curly brackets.
While this doesn't create a syntax error, coding convention in Java is to use curly brackets if you have any code inside an if/for/while statement. This is to avoid confusion and makes the code easier to read.
Though looking at your code, you are enclosing the code being executed in the if statement.
