请问哪位大侠知道这个程序有什么错误,谢谢!
package edward;
public class Triangle{
double sideA,sideB,sideC;
boolean isTriangle;
public Triangle(double a,double b,double c){
if(a+b>c&&b+c>a&&a+c>b){
isTriangle=ture;
}
else{
isTriangle=flase;
}
public void 计算面积{
if(isTriangle){
double p=(sideA+sideB+sideC)/2.0;
double area=Math.sqrt(p*(p-sideA)*(p-sideB)*(p-sideC));
System.out.println("是一个三角形,面积为:"+area);
}
else{
System.out.println("不是一个三角形,不能计算面积");
}
public void 修整三边(double a,double b,double c){
sideA=a;
sideB=b;
sideC=c;
if(a+b>c&&a+c>b&&b+c>a){

public static void main(String args[]){

}
}
------解决方案--------------------少了闭合的} 还有中文名字!
------解决方案--------------------错误百出!
都是小错误,这种错误LZ因该学会自已解决,这是必须的!
另外中文可以,只是不符合JAVA编程规范。
