//import java.util.People;
public class People
{
private double height;
public double getHeight(){
return height;
}
public void setHeight(double newHeight){
height = newHeight;
}
}
public class NewObject{
public static void main(String[] args){
People LiLei = new People();
LiLei.setHeight(150.0);
System.out.println("LiLei的身高是"+LiLei.getHeight());
}
}
运行报错：
shiyanlou:project/ $ javac NewObject.java [0:48:46]
NewObject.java:2: 错误: 类People是公共的, 应在名为 People.java 的文件中声明
public class People
^
1 个错误
把两个程序单独成独立程序也是报错，之间使用import.java.util.People.不管用
