Java Grect 和私有(private)静态错误

Question

这是代码:

    package main;

import java.awt.*;
import acm.graphics.*;
import acm.program.*;

public class AjorBandi extends GraphicsProgram{

public void run(){
    private static final BRICK_TOOL=30 ;
    private static final BRICK_ARZ = 10;
    int x,y;
    x=0;
    y=100;
    for(int ii=0;ii<14;ii++){
    for(int i= 0;i<14;i++){
        Grect rect = new Grect(x,y,BRICK_TOOL,BRICK_ARZ);
        add(rect);
        x+=30;
        i-=1;       


    }
    y+=10;
    x+=15;


    }

}

}

这是来自 eclipse 的 Grect 错误消息:

    Multiple markers at this line
- Grect cannot be resolved to a 
 type
- Grect cannot be resolved to a 
 type

这是私有(private)静态错误消息:

    Multiple markers at this line
- Line breakpoint:AjorBandi [line: 10] - run()
- Syntax error on token "final", float expected
- Illegal modifier for parameter BRICK_TOOL; only final is 
 permitted

我的 Eclipse IDE 出现编译错误。这两个错误的问题是什么？

Answer 1

你的两个变量

private static final BRICK_TOOL=30 ;
private static final BRICK_ARZ = 10;

有两个问题。

它们应该在类级别声明，而您错过了最重要的东西，类型。我举了一个例子，我使用 int 来表示它们:

public class MyClass
{
    private static final int BRICK_TOOL = 30;
    private static final int BRICK_ARZ = 10;

    myMethod()
    {
        //do stuff here
    {
}
