question 6

Multiple Choice

Consider a class that uses the following variables to implement an array-based stack:
String [ ] s = new String[100];
Int top = -1;// Note top == -1 indicates stack is empty
A method that implements a String pop() operation can be written as

• A) if (top == -1)
• Throw new RuntimeException("Empty Stack");
• Top --;
• String temp = s[top];
• S[top] = null;
• Return temp;
• B) if (top == -1.
• Throw new RuntimeException("Empty Stack".;
• S[top] = null;
• Top--;
• Return s[top ];
• C) if (top == -1.
• Throw new RuntimeException("Empty Stack".;
• String temp = s[top];
• S[top] = null;
• Top--;
• Return temp;
