Question

What value is printed by the following code?

int a = 1;int b = 2;if (a <= 2 && b < a){a *= 2;}else{b *= 2;}if (!(a == 3 || b == 4)){a *= 3;}else{b *= 5;}System.out.println(a + " " + b);

Answer 1

The Java code conducts a series of conditional checks and modifies the values of two variables. After executing the if-else statements, the resulting output printed by the code is "1 20".

Step-by-step explanation:

The given code is written in Java and includes control flow statements such as if-else and conditional operators like && (AND) and || (OR). The code snippet executes a series of conditional checks and arithmetic operations to determine the values of variables a and b. Initially, a is set to 1 and b is set to 2.

First, the code checks if a is less than or equal to 2 and if b is less than a. Since b is not less than a, it enters the else block, where b is doubled, changing the value of b to 4.

Next, the code checks if a is not equal to 3 or b is not equal to 4. Since b is equal to 4, it enters the else block, where b is multiplied by 5, giving b a final value of 20. Variable a remains unchanged at 1.

Finally, the program prints out the values of a and b. The printed output will be "1 20".
