个人原创代码：Java异常处理程序。编写Java Application程序，自定义类Sanj，其中有成员 x,y,z,作为三边长，构造方法Sanj(a,b,c)分别给x,y,z赋值,方法求面积getArea和显示三角形信息(三个边长)showInfo，这2个方法中当三条边不能构成一个三角形时要抛出自定义异常NotSanjiaoException，否则显示正确信息。在另外一个类中的主方法中构造一个Sanj对象(三边为命令行输入的三个整数)，显示三角形信息和面积，要求捕获异常。-Personal original code: Java exception handling procedures.Write a Java application program, Sanj custom classes, including members of the x, y, and z, as long, triangular and assignment constructor Sanj (a, b, and c), respectively, to x, y, z, and the area the getArea and display a triangle(three side length) showInfo these two methods when the three sides can not form a triangle to throw self-defined exceptions NotSanjiaoException, or display the correct information. The Sanj object (triangular command line input three integers) a method to construct a display triangle and the area required to capture the exception.
