需要输入参数的程序用Eclipse怎么运行？

Question

class NewRoot { public static void main(String[] arguments) { int number = 100; String count = "25"; float sentence = 17.5F; if(arguments.length > 0) { number = Integer.parseInt(arguments[0]); } System.out.println("The square root of " + number + " is " +Math.sqrt(number)); System.out.println(Math.sqrt(Integer.parseInt(count))); System.out.println("My sentence has been reduced to " + sentence + " years."); } } 像这样的输入arguments[0]，就可以改变输出值，在dos里可以输入java NewRoot 200实现，但是在Eclipse要怎么办才可以呢？ 有人说在console里输入，但是我试了一下，console是只读的，不能打字。
