定义Penguin.class
主程序
packageJava0719;
publicclassPenguin{
Stringname;
inthealth;
intlove;
Stringsex;
publicPenguin(Stringname,inthealth,intlove,Stringsex){
this.name=name;
this.health=health;
this.love=love;
this.sex=sex;
}
publicvoidprint(){
System.out.println("名字"+this.name+"健康"+this.health+"亲密"+this.love+"性别"+this.sex);
}
publicstaticvoidmain(String[]args){
Penguinpgn=newPenguin("美美",80,20,"Q仔");
pgn.print();}
}
输出结果为
名字美美健康80亲密20性别Q仔
定义Penguin.class
现在我把文件改成
packageJava0719;
classPenguin{
Stringname;
inthealth;
intlove;
Stringsex;
publicPenguin(Stringname,inthealth,intlove,Stringsex){
this.name=name;
this.health=health;
this.love=love;
this.sex=sex;
}
publicvoidprint(){
System.out.println("名字"+this.name+"健康"+this.health+"亲密"+this.love+"性别"+this.sex);
}
publicclassTest{
publicstaticvoidmain(String[]args){
Penguinpgn=newPenguin("美美",80,20,"Q仔");
pgn.print();}
}
}
结果错误:找不到或无法加载主类Java0719.Test
