Java代码，由Component派生出CPU类（CPU）和显卡类（Vedio）。CPU类增加了新的属性：核心数，Vedio类增加了属性：显存。

以下是Java代码：

import java.awt.Component;

public class CPU extends Component {
    private int coreCount;

    public CPU(int coreCount) {
        this.coreCount = coreCount;
    }

    public int getCoreCount() {
        return coreCount;
    }

    public void setCoreCount(int coreCount) {
        this.coreCount = coreCount;
    }
}

public class Vedio extends Component {
    private int memorySize;

    public Vedio(int memorySize) {
        this.memorySize = memorySize;
    }

    public int getMemorySize() {
        return memorySize;
    }

    public void setMemorySize(int memorySize) {
        this.memorySize = memorySize;
    }
}
