浙江工业大学计算机学院《Java程序设计》编程题——赵小敏自编2011一、程序设计基础1、用for语句实现下面的程序ForDemo.java：从10～100以内能被2整数但不能被3整除的整数，要求每行按10个数(数与数之间有一个空格间隔)的形式对其输出。程序的源文件名为PrintPrimeNumber.java。类名为PrintPrimeNumber。2、编写一个getY（doublet）方法，返回值按下列函数计算：t2-10≤t＜1t3-2·t-21≤t＜3y＝t2-t·sint3≤t＜5t 15≤t＜7t-1其它3、编写一个java应用程序，从键盘输入x，利用下列台劳公式计算cos(x)的值，并输出（要求精确到0.000001）。台劳公式为：cos(x)=1－x2/2! x4/4!－x6/6! x8/8!－„„4、编写Java独立应用程序，先产生1个随机数n（要求0
