代码如下：

package 继承;public class Student {	private String name ;		private int age ;		private String college ;	private String depart ;		public Student (){}		public Student (String name , int age , String college , String depart)	{			this.setName(name);			this.setAge(age);			this.setCollege(college);		this.setDepart(depart);			}		public void setName(String name){			this.name = name;			}		public void setAge(int age)	{				this.age = age ;		}	public void setCollege(String college){				this.college = college ;		}		public void setDepart(String depart){			this.depart = depart ;			}		public String getName(){			return this.name ;		}	public int getAge(){			return this.age ; 			}		public String getCollege(){					return this.college ;				}	public String getDepart(){			return this.depart;		}	public String getInfo(){			return "学生信息如下:" + "\n" +			"姓名:" + this.getName() + "\n" +						"年龄:" + this.getAge() + "\n" +			"学校:" + this.getCollege() + "\n" +							"学院:" + this.getDepart(); 			}	} 	 class  test1{			public static void main (String args[]){				Student stu1 = new Student("张三" , 22 , "shu" ,					"computer science and techololege") ;					System.out.println(stu1.getInfo());	}		}
