java - 如何在 java me 中有效地连接两个 vector 的数据？

Question

我的程序中有两个 Vector，我想加入它们的数据

Vector a=new Vector();
Vector b=new Vector();

Answer 1

Vector a = new Vector();
Vector b = new Vector();

// populate vectors a and b
// ...

Vector c = new Vector();

for(Enumeration e = a.elements(); e.hasMoreElements();) {
    c.addElement(e.nextElement());
}
for(Enumeration e = b.elements(); e.hasMoreElements();) {
    c.addElement(e.nextElement());
}

// c now contains all elements from a followed by all elements from b
