下列程序的运行结果是（）。 public class Test public static void main ( String [ ] args ) int count = 0 for( int i = 1 i < 5 i = 2) for( int j = 1 j< = 10 j = 3) count System .out .print (count ) _

分析下列程序，写出其功能。 import java.applet.*; import java.awt.*; import java.awt.event.*; public class Test extends Applet implements MouseListener { final int number = 5; int count = 0; Image[] card = new Image[number]; public void init() { setSize(1200,1000); addMouseListener(this); for (int i = 0; i < number; i++) { card[i] = getImage(getCodeBase(), i+".jpg"); } } public void paint(Graphics g) { if ((card[count]) != null) g.drawImage(card[count], 10,10,card[count].getWidth(this),card[count].getHeight(this), this); } public void mousePressed(MouseEvent e) { count = (count + 1) % number; repaint(); } public void mouseReleased(MouseEvent e) {} public void mouseEntered(MouseEvent e) {} public void mouseExited(MouseEvent e) {} public void mouseClicked(MouseEvent e) {} }

下列程序的输出结果是 _____ 。 #include using namespace std; class Test { public: Test() { cnt++; } ~Test() {cnt--; } static int Count() { returncnt;} private: static int cnt; }; int Test::cnt = 0; int main() { cout << Test::Count()<<' '; Test tl, t2; Test* pT3 = new Test; Test* pT4 = new Test; cout << Test::Count()<<' '; delete pT4; delete pT3; cout << Test::Count()<< endl; return 0; }

以下哪个方法是正确的？ A: public static int Sum(int n, params int[] val){ int count = 0; foreach (int a in val){ count = count + a; } return count + n;} B: public static int Sum(params int[] val, int n){ int count = 0; foreach (int a in val){ count = count + a; } return count + n;} C: public static int Sum(params int[] v1, params int[] v2){ int c1 = 0, c2 = 0; foreach (int a in v1){ c1 = c1 + a; } foreach (int a in v2){ c2 = c2 + a; } return c1 + c2;} D: public static int Sum(params int[] v, char ch){ int c = 0; foreach (int a in v){ c = c + a; } return c + ch;}

给定Java代码如下所示，则编译运行后，输出结果是。 class Parent { public void count() { System.out.println(10%3); } } public class Child extends Parent{ public void count() { System.out.println(10/3); } public static void main(String args[]) { Parent p = new Child(); p.count(); } }
