11/7/2021 Java实验总结

    import java.util.Scanner;

//when using:
    Scanner s=new Scanner(System.in);
	System.out.println("Name:");
	Name=s.next();

    CLASSNAME[] name=new CLASSNAME [i];
 // 为对象分配空间！ 
    name[i]=new CLASSNAME ();    //此处使用构造函数

#对象数组的创建

示例代码：

abstract class Abs
{
    abstract float getFloat () ;
}
public class AbstractTest extends Abs 
{
	 private float f1= 1.0f;
	 private float getFloat (){
	 return f1;
}

错误原因：Cannot reduce the visibility of the inherited method from Abs.
