第一关

主函数：

    public static void main(String[] args) {/********** Begin **********///创建Dog对象//设置Dog对象的属性Dog wuhuarou = new Dog("五花肉","棕色","阿拉斯加");//输出小狗的属性System.out.println("名字：" + wuhuarou.getName()   + "，毛色：" + wuhuarou.getColor()   + "，品种：" + wuhuarou.getVariety() );//调用方法wuhuarou.eat();System.out.println();wuhuarou.run();/********** End **********/}

其他类

class Dog
//在这里定义Dog类
{/********** Begin **********/String name;String color;String variety;public Dog(String name,String color,String variety){this.name = name;this.color = color;this.variety = variety;}public Dog(){}public void eat(){System.out.print("啃骨头");}public void run(){System.out.print("叼着骨头跑");}/********** End **********/public String getName() {return name;}public void setName(String name) {this.name = name;}public String getColor() {return color;}public void setColor(String color) {this.color = color;}public String getVariety() {return variety;}public void setVariety(String variety) {this.variety = variety;}
}

第二关

主函数

public static void main(String[] args) {Scanner sc = new Scanner(System.in);String name = sc.next();String sex = sc.next();/********** Begin **********///分别使用两种构造器来创建Person对象Person person = new Person();Person person2 = new Person(name,sex);/********** End **********/}

其他

    class Person
{//创建Person对象，并创建两种构造方法
/********** Begin **********/
String name;
String sex;public Person(){System.out.println("一个人被创建了");}public Person(String name, String sex) {this.name = name;this.sex = sex;System.out.println("姓名："+getName()+"，性别："+getSex()+"，被创建了");}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getSex() {return sex;}public void setSex(String sex) {this.sex = sex;}
/********** End **********/
}

第三关

第四关

主函数

    public static void main(String[] args) {Scanner sc = new Scanner(System.in);String name = sc.next();int age = sc.nextInt();String sex = sc.next();Person p = new Person(name,age,sex);p.display();}

class Person{String name = "张三";int age = 18;String sex = "男";/********** Begin **********/public Person(String name,int age,String sex){this(age);this.name = name;this.sex = sex;}public Person(int age){this.age = age;}public void display(){System.out.println("name：" +name);System.out.println("age：" + age);System.out.println("sex：" + sex);}/********** End **********/
}

第五关

注意这个题是分文件编写的
还有就是第一次可能出现问题（多半是网络问题），再试一次

/********** Begin **********/
//在这里添加包名  step4
package step4;
//创建类 添加属性和方法
public class WuMingFen {String theMa ;int quantity ;boolean likeSoup ;public WuMingFen() {theMa = "酸辣";quantity =2;likeSoup =true;}public WuMingFen(String theMa,int quantity){this.theMa = theMa;this.quantity = quantity;likeSoup = false;}public WuMingFen(String theMa, int quantity, boolean likeSoup) {this.theMa = theMa;this.quantity = quantity;this.likeSoup = likeSoup;}public String getTheMa() {return theMa;}public void setTheMa(String theMa) {this.theMa = theMa;}public int getQuantity() {return quantity;}public void setQuantity(int quantity) {this.quantity = quantity;}public boolean isLikeSoup() {return likeSoup;}public void setLikeSoup(boolean likeSoup) {this.likeSoup = likeSoup;}public void check(){System.out.println("面码：" +getTheMa()+ "，粉的份量："+getQuantity()+"两，是否带汤："+likeSoup);}
}

public class Test {public static void main(String[] args) {Scanner sc = new Scanner(System.in);String theMa = sc.next();int quantity = sc.nextInt();boolean likeSoup = sc.nextBoolean();/********** Begin **********///使用三个参数的构造方法创建WuMingFen对象  取名 f1WuMingFen f1 = new WuMingFen(theMa,quantity,likeSoup);//使用两个参数的构造方法创建WuMingFen对象  取名 f2WuMingFen f2 = new WuMingFen(theMa,quantity);//使用无参构造方法创建WuMingFen对象  取名 f3WuMingFen f3 = new WuMingFen();//分别调用三个类的 check方法f1.check();f2.check();f3.check();/********** End **********/}
}

第六关

public class Test {/********** Begin **********/static String name = "楚留香";static{System.out.println("hello educoder");}public static void main(String[] args) {System.out.println("我叫" + name);study();}public static void study(){System.out.println("我喜欢在educoder上学习java");}/********** End **********/
}
