我对Java真的很陌生，开始自己研究它....我下载了netbeans和Eclipse，两者给了我相同的结果..他们不运行代码（卡在运行）也不让我调试它- Eclipse 调试器和 Netbeans - 没有响应：？我没有什么错..我不知道，因为我无法调试..
这是我的代码：我正在尝试检查回文：

private Object[] Stack_Array = null;

this(100);
}
protected void finalizer() {
Stack_Array = null;
}
final public boolean empty() {
return top == 0;
}
final public boolean full() {
return top == Stack_Array.length;
}
public void push(Object token) {
if (!full()) {
Stack_Array[top] = token;
top++;
}
}
public Object pop() {
Object Value_return = -999;
if (!empty()) {
Value_return = Stack_Array[top];
top--;
}
