第一个：
package domain
public class Vehicle{
private static double KG_TO_NEWTON = 9.8;
private double Load;
private double maxLoad;
public Vehicle (double max_load){
Load = 0.0;
maxLoad = KiloToNewts(max_load);
}
public double getLoad() {
return NewtsToKilo(Load);
}
public double getMaxLoad(){
return NewtsToKilo(maxLoad);
}
public boolean addBox(double weight){
double weight_in_newtons = KiloToNewts(weght);
boolean result = true;
if ((weight_in_newtons + Load) > maxLoad){
result = false;
}else {
Load = Load + weight_in_newtons;
}
return result;
}
private double KiloToNewts(double weight){
return (weught * KG_TO_NEWTON);
}
}
错误如下：
---------- javac ----------
Vehicle.java:2: ';' expected
public class Vehicle{

1 e
package domain

private static double KG_TO_NEWTON = 9.8;
private double Load;
private double maxLoad;

public double getLoad() {

public double getMaxLoad(){
return NewtsToKilo(maxLoad);
}
public boolean addBox(double weight){
double weight_in_newtons = KiloToNewts(weght);
boolean result = true;
if ((weight_in_newtons + Load) > maxLoad){
result = false;
}else {
Load = Load + weight_in_newtons;
}
return result;
}
private double KiloToNewts(double weight){
return (weught * KG_TO_NEWTON);
}
}
错误如下：

你以前学VB吗？错误都是一样的，后面得多加个；号啊，如第一题中应该是
package domain ；//要加；号
第二题下面所有的
System.out.println("Add box #1 (500kg):"+Vehicle.addbox(500.0))后面得加；号，即
System.out.println("Add box #1 (500kg):"+Vehicle.addbox(500.0)) ；
你改后看看还有什么问题。
System.out.println("Add box #2 (250kg):"+Vehicle.addbox(250.0)) ;
你这里没打;号 自己好好找找
package domain 后面少个分号，貌似
第二题是这样的，你把Vehicle和vehicle 弄混了
Vehicle是类，vehicle是类的对象。这里应
System.out.println("Vehicle load is" +vehicle.getLoad()+"kg");
