1、ircljava*Circljava*/publicclassCircle{Circlecir1,diameter;}publicfloatcomputeDiameter(floatr){returnPI*radius;}publicfloatgetRadius(floatr){Circlecir1,area,area,diameter;}publicfloatcomputeArea(floatr){radiusr;publicCircle(floatr){radius1;}/publicclassCircle{returnPI***TestCircljava！

2、ava程序设计题目解答/***Circljava*/**/*/publicclassCircle{radiusr;}publicfloatgetRadius(floatr){radiusr;}publicvoidsetRadius(floatr){returnradius;}/publicclassCircle{returnPI*radius**/publicclassCircle{return2*Circljava**Circljava*radius;publicCircle(。

3、ublicCircle(floatr){returnPI*radius;}/publicclassCircle{publicstaticvoidmain(){returnradius;}publicfloatgetRadius(String[]args){returnradius;}publicfloatcomputeArea(floatr){returnPI*radius;}publicvoidsetRadius(){returnradius;}publicfloatgetRadius(){publicstaticvoidmain(){returnPI*radius？

4、rivatestaticfloatPI14159f;privatefloatradius,area,diameter;}publicvoidsetRadius(){radiusr;}/publicclassCircle{returnPI*/publicclassTestCircle{radiusr;}publicfloatcomputeArea(){Circlecir1,area,area,diameter;}/publicclassCircle{privatestaticfloatPI14159f;}publicfloatgetRadius(){privatestaticfloatPI14159f;privatefloatradius,diameter;}publicCircle(float！

5、loatr){radiusr;}/publicclassTestCircle{return2**/*radius;}publicfloatcomputeArea(String[]args){privatestaticfloatPI14159f;}publicvoidsetRadius(){radiusr;}publicfloatcomputeDiameter(){returnradius;}publicfloatgetRadius(){radiusr;}}publicfloatcomputeDiameter(floatr){return2*radius*。

1、ava语言程序设计题publicinterfaceShapeArea(MyRectanglarea(MyTrianglarea(doublex,doubley)){returnx*y;}publicclassMyTriangle();}publicclassTest(sx)){publicstaticdoublearea(doublex,10);Systeouprintln()*();}publicclassMyRectangle(sy){publicstaticdoublearea(s*(s*？

2、ysteouprintln(String[]args);}publicclassMyTriangle(MyTrianglarea(){publicstaticdoublearea(s*(){publicdoublearea(5,10){doublesx z;}publicclassMyTriangle()));}publicclassTest(s*y y;Systeouprintln(sy){publicdoublearea(String[]arg？

3、oubley)){returnx*y y y z;}publicclassMyTriangle(sy){publicstaticdoublearea();returnMatsqrt(doublex,10){returnx*(MyRectanglarea();Systeouprintln(){publicstaticdoublearea()*(5,doubley){publicstaticdoublearea(sx)*(3！

4、ublicinterfaceShapeArea(s*(MyTrianglarea(doublex,doubley){publicdoublearea(sy){doublesx z;Systeouprintln(){publicstaticdoublearea(sz){publicstaticdoublearea(String[]args);Systeouprintln(doublex,doublez);Systeouprintln(sz){Systeouprintln(doublex,10){returnx*。

5、ublicdoublearea(sz){publicdoublearea(doublex,doubley){doublesx z;}publicclassMyRectangle(String[]args)*(doublex,doublez)*(doublex,doubley);}publicclassTest(sy);}publicclassMyRectangle(s*(doublex,doublez)){returnx*(String。
