This is Java program please help

Show what is written by the following segment of code, given that item1, item2, and item3 are int variables, and stack is an object that fits our abstract description of a stack. Assume that you can store and retrieve variables of type int on stack. item1 = 1: item2 = 0: item3 = 4: stack.push(item2): stack.push(item1): stack.push(item1 + item3): item2 = stack.top(): stack.push (item3*item3): stack.push(item2): stack.push(3): item1 = stack.top(): stack.pop(): System.out.println(item1 +"" + item2 +"" + item3): while (!stack.isEmpty()) } item1 = stack.top(): stack. pop(): System.out.println(item1): }

Explanation / Answer

item1 = 1;

item2 = 0;

item3 = 4;

stack.push(item2); // top->0

stack.push(item1); // top->1 0

stack.push(item1+item3); // top-> 5 1 0

item2 = stack.top(); // item2 = 5 , top->5 1 0

stack.push(item3*item3); // top-> 16 5 1 0

stack.push(item2); // top-> 5 16 5 1 0

stack.push(3); // top->3 5 16 5 1 0

item1 = stack.top(); // item1 = 3 + 5 + 4 = 12

stack.pop(); // top-> 5 16 5 1 0

System.out.println(item1 + " "+item2+" "+item3); // 3 + 5 + 4 = 12

while(!stack.isEmpty())

{

item1 = stack.top();

stack.pop();

System.out.println(item1); // 5 16 5 1 0

}

Output:

12

5 16 5 1 0
