今天的作业是：
要验证此等式成立，要用到循环语句和判断语句，以下是我的代码：
package quickstart;
public class Math1 {
public static void main(String args[]) {
int res = 0;
for (int x = 3; x < 6; x = x + 1) {
res = res + x * x * x;
System.out.print(res);
System.out.print("\n");
}
int res2 = 6 * 6 * 6;
if (res == res2) {
System.out.print("OK,第1个算式相等！");
}
res = 0;
for (int x = 6; x < 70; x = x + 1) {
res = res + x * x * x;
System.out.print(res);
System.out.print("\n");
}
res2 = 180 * 180 * 180;
if (res == res2) {
System.out.print("OK,第2个算式相等！");
}
}
}
