注: 在class employee前面不能加public

import java.io.*;class employee {    private String employeeName;    private int employeeNo;    private double employeeSalary;    public void setEmployeeName(String name) {        employeeName = name;    }    public void setEmployeeSalary(double salary) {        employeeSalary = salary;    }    public void setEmployeeNo(int no) {        employeeNo = no;    }    public String toString() {        String s;        s = "编号: " + employeeNo + "  姓名: " + employeeName + "  工资: " + employeeSalary;        return s;    }}public class test_employee {    public static void main(String args[]) {        employee ep;        ep = new employee();        ep.setEmployeeNo(10001);        ep.setEmployeeSalary(5000);        ep.setEmployeeName("Mary");        System.out.print(ep.toString());        System.out.println();    }}// 编号: 10001  姓名: Mary  工资: 5000.0
