Conditional Statement(JS)

Conditional Statement(Java)

There are totally 5 kinds of conditional statements will be selected:

• if
• if-else
• if-else if-else
• try-catch
• switch

For if statement, a condition will be generated according to declared variables in the test case. Here are examples:

Always True / False	Boolean Expression	Variable Declaration
Always True	GTe.length <= 10&&GTe[8]==-152072164	[int[] GTe = { 0, 8, 1659535291, 8, 0, 2, 8, 6, -152072164, 0 };]
Always False	myjvm_par0 > 7	[int myjvm_par0 = 6;]
