急！！！JAVA课堂实验编程，求答案！！追分急！！
纯手打，2.（3）没搞清那个命令行是什么意思，所以没写
package student;
public class Student {
private String college;
private String major;
private String classes;
private String name;
private int oop;
private int network;
private int sql;
private int sum;
//无参构造函数
public Student(){}
//有参构造函数
public Student( String college,
String major, String classes,
String name, int oop, int network,
int sql) {
super();
this.college = college;
this.major = major;
this.classes = classes;
this.name = name;
this.oop = oop;
this.network = network;
this.sql = sql;
}
//成员方法
public int sum(){
return oop+network+sql;
}
//getter,setter方法
public String getCollege() {
return college;
}
public void setCollege(String college) {
this.college = college;
}
public String getMajor() {
return major;
}
public void setMajor(String major) {
this.major = major;
}
public String getClasses() {
return classes;
}

this.classes = classes;
}
public String getName() {

}

}
public int getNetwork() {
return network;
}
public void setNetwork(int network) {

}
public int getSql() {
return sql;
}
public void setSql(int sql) {

}
//toString方法
@Override
public String toString() {
return "姓名："+getName()+" "+"学院："+getCollege()+" "+"专业："+getMajor()
+" "+"班级"+getClasses()+" "+"总成绩："+sum();
}
}
//测试类
