Java SE 6.0前11章示的示例代码,简单易学

package wyf;
public class Sample7_17
{
	//声明并初始化静态成员变量count
	static int count=0;
	int selfCount=0;
	public Sample7_17()
	{
		//对成员变量进行操作
		count++;
		selfCount++;
	}
	public static void main(String[] args)	
	{
		//创建三个Sample7_17对象
		Sample7_17 s1=new Sample7_17();
		Sample7_17 s2=new Sample7_17();
		Sample7_17 s3=new Sample7_17();
		//打印输出成员变量
		System.out.println("静态成员变量count的值分别为：s1.count="
		      +s1.count+", s2.count="+s2.count+", s3.count="+s3.count);
	    System.out.println("非静态成员变量count的值分别为：s1.selfCount="
	          +s1.selfCount+", s2.selfCount="+s2.selfCount+", s3.selfCount="+s3.selfCount);
