java 三角形、梯形和圆形的类封装
帮忙改正一下错误（下面标出的四个错误,只截取了部分代码,因为装不下）,
package shiyan1;
class Trangele{
double sideA,sideB,sideC,area,length;
boolean boo;
（错误）public Trangle(double a,double b,double c)
{
\x05sideA=a;sideB=b;sideC=c;
\x05if(a+b>c&&a+c>b&&b+c>a)
\x05{
\x05\x05boo=true;
\x05}
（错误）public double getArea()
{if(boo)
{
\x05double p=(sideA+siedB+sideC)/2.0;
\x05area=Math.sqrt(p*(p-sideA)*(p-sideB)*(p-sideC));
\x05return area;
（错误）public void setABC(double a,double b,double c)
{
\x05sideA=a;sideB=b;sideC=c;
\x05if(a+b>c&&a+c>b&&b+c>a)

public class AreaAndLength

\x05\x05Circle circle=null;
\x05\x05（错误）Trangle trangle;
\x05\x05Lader lader;
\x05\x05circle=new Circle(10);
\x05\x05（错误）trangle=new Trangle(3,4,5);
lader=new Lader(3,4,10);
\x05\x05length=circle.getLength();

你稍等一下,我把代码测试通过后.给你贴出来您有以下几处错误：1,Trangle书写错误 Tranglepublic Trangle(double a,double b,double c) ===》public Trangele(double a,double b,double c)（错误）public Trangle(dou...
