Java loop puzzles

 

Bloch talked about many Java puzzles. Today I will share them with you.

0-cycle subject

Please write a variable declaration and place it before the following loop to make this loop an infinite loop.

For (INT I = start; I <= start + 1; I ++ ){

}

Here, start is an undefined variable. We need to define it.

If you are familiar with int, you may get the correct answer:

Int start = integer. max_value-1;

Why? Haha, because Int. max_value + 1 = int. Min-value.

 

You need to consider the following. # ^ _ ^ #

1 loop Operator

What kind of statement can make the following loop infinite?

While (I = I + 1 ){

}

2. The Bride of the loop

Provide an I statement so that the following loop is an infinite loop.

While (I! = I ){

}

3. The love of the loop Operator

Provide an I statement so that the following loop is an infinite loop.

While (I! = I + 0 ){

}

4. The ghost of the loop

Provide an I statement so that the following loop is an infinite loop.

While (I! = 0 ){

I >>>= 1;

}

5. cursing the loop

Provide declarations on I and j so that the following loop is an infinite loop.

While (I <= J & J <= I & I! = J ){

}

6. The person in the loop met the prodigal person.

Provide an I statement so that the following loop is an infinite loop.

While (I! = 0 & I =-I ){

}
