Question

Give the Java statement that produced the following ijvm code, and briefly describe what this piece of code does.

bipush 0
istore i
bipush 0
istore j
agn: iload i
bipush 1
iadd
istore i
iload i
iload j
iadd
istore j
iload i
bipush 5
if_icmpeq stop
goto agn
stop:
a) i++; j += i; if (i == 5) break; - Increments i, adds it to j, and breaks when i equals 5.
b) i = 0; j = 0; while (i < 5) i++; j += i; - Initializes i and j, then increments i and adds it to j in a loop until i equals 5.
c) int i = 0, j = 0; do i++; j += i; while (i != 5); - Initializes i and j, then increments i and adds it to j in a do-while loop until i equals 5.
d) int i = 0, j = 0; for (; i < 5; i++) j += i; - Initializes i and j, then increments i and adds it to j in a for loop until i equals 5.

Answer 1

The Java statement that would produce the given ijvm code is a 'while' loop that initializes variables i and j to 0, increments i, and adds it to j until i equals 5.

Step-by-step explanation:

Java Code:

i = 0;
j = 0;

while (i < 5) {
i++;
j += i;
}

This piece of code initializes the variables i and j to 0.

It then enters a while loop that continues as long as i is less than 5. Within the loop, i is incremented by 1 and added to j.

This continues until i reaches 5, after which the loop terminates.
