题目很简单~最好在~星期1之给于答案~谢谢了~要是有相关的代码也可以

public class Vehicle{ private char type; private int number; private String time;

public Vehicle(char type,int number,String t){ this.type = type; this.number = number; time = t; }

public void setType(char c){ type = c; }

public char getType(){ return type; }

public String toString(){ String result = ""; result += "The type of the car is: "+type+",the number is: "+number+",enter time: "+time+"."; return result; } }// end of Vehicle class

public class TestCar{ public static void main(String[] args){ Vehicle v = new Vehicle('L', 324563, "07:32:43"); System.out.println(v); } } //end of TestCar class

// I am not sure if this is what you want, but i suspect so :P

public class ClassData { private String name; // you may need this as public private int number; // this as well

ClassData(String theName, int theNumber) { name = theName; number = theNumber; }

public String getName(){ return name; }

public int getNum(){ return number; } }//end of ClassData class

public class AllClass{ ClassData data[] = new ClassData[200]; int classCount = 0;

public void addClass(String theName, int theNumber) { data[classCount] = new ClassData(theName,theNumber); classCount++; }

public int getNumber(String className) { for(int i = 0; i<classCount; i++){ if(data[i].getName().equals(className)) // i am not sure if i can use the accessor method here return data[i].getNum();//also not sure if i can use either } return -1; } }//end of AllClass class

// maybe you can declear String className and int number as public then you dont need the accessor method // but this is kind of unusual i think...

本来是想做三的，可是你的题目我不太清楚什么意思：　窗口上会显示信息"TRUE"　？？　这个是用g.drawString()还是写在一个TextField里，还是直接System.out.print() ???还有可不可以在constructor method里加一个boolean b;用来判断是应该＂写＂true 还是"false"?

我帮另一个人都做完了，你可以问他要，QQ：11793485

的第一題答案好像有問題哦?

public class Vehicle{ private char type; private int number; private String time;

裏面的public 去掉就沒問題了

哇。几百年前的。。。

Vehicle.java 和 TestCar.java是两个不同的class 把他们分开存。我写在一起是因为是一道题目。。

sorry for the confusion...
