java - 绘制输入输出交换的函数图

Question

有没有办法在单独的类中绘制以下代码输出的值的图表。

import java.util.Scanner;

public class scannerNumber {
    public static void main(String []args) {

    Scanner originalNumber = new Scanner(System.in); // number for input

    System.out.println("Enter a number: "); // asks for input

    int firstNumber = originalNumber.nextInt();

    double secondNumber = Math.abs((firstNumber*Math.sin(firstNumber)));

    System.out.println("Your new number is: " + secondNumber);

    originalNumber.close();

    }

}

Answer 1

Scanner originalNumber = new Scanner(System.in); // number for input

ArrayList<Double> results = new ArrayList<Double>;// array for results

System.out.println("Enter a number: "); // asks for input

int firstNumber = originalNumber.nextInt();

for(int i=0; i<=firstNumber; i++){
    double secondNumber = Math.abs((firstNumber*Math.sin(firstNumber)));

    results.add(secondNumber);//add results to an array
}
for(int k:results)
    System.out.print(k+" ");

originalNumber.close();

这将创建一个包含 y 值的数组，而 x 介于 [0,firstNumber] 之间 请注意，这并不是您问题的完整答案。你应该从基础开始。 complete tutorial for function drawing in java 。您可以使用本教程，但首先查看 java 的 gui。
