Teacher类 

package tiku;

public class Teacher {
	private String name;
	private int age;
	public Teacher() {
		//无参构造方法
	}
	public Teacher(String name, int age) {
		//有参构造方法
		this.name = name;
		this.age = age;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
}

测试类

package tiku;
public class test {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Teacher zhangsan = new Teacher();
		zhangsan.setName("zhangsan");
		zhangsan.setAge(30);
		Teacher lisi = new Teacher("lisi",28);
		System.out.println("name:"+zhangsan.getName()+",age:"+zhangsan.getAge());
		System.out.println("name:"+lisi.getName()+",age:"+lisi.getAge());
	}
}
