我有简单的课程
import java.io.PrintStream;

*/
public Lab1_1(float a, float b, float c) {
this.a = a;
this.b = b;
this.c = c;
}
/**

*/
public String calculate() {
float discriminant = b * b - 4 * a * c;
if (discriminant > 0) {
double result1 = (-b + Math.sqrt(discriminant)) / (2 * a);
double result2 = (-b - Math.sqrt(discriminant)) / (2 * a);
return "x1 = " + result1 + ";" + "x2 = " + result2;
} else if (discriminant == 0) {
double result = -b / (2 * a);
return "x1 = " + result + ";" + "x2 = " + result;
} else throw new ArithmeticException("Discriminant is less than zero! The result is a complex number!");
}
public static void main(String[] args) {
try{
if (args.length < 3) {
new PrintStream(System.out, true, "UTF-8").println("Number of input arguments is less than 3");
return;
}
try{
new PrintStream(System.out, true, "UTF-8").
println(
new Lab1_1(Float.parseFloat(args[0]),Float.parseFloat(args[1]),Float.parseFloat(args[2])).
calculate());
}catch(ArithmeticException e) {
System.out.println(e.getMessage());
}
}
catch(Exception e) { e.printStackTrace(); }
}
}
但是当我在Lab1_1 html文件中生成文档javadoc -d c:\mypath\home\html Lab1_1.java
时,没有变量字段。
我的评论有什么问题?
