第二章第十八题（打印表格）(Print a table)

2.18（打印表格）编写程序，显示下面的表格。将浮点数值类型转换为整数。

a	b	pow(a,b)
1	2	1
2	3	8
3	4	81
4	5	1024
5	6	15625

2.18(Print a table) Write a program that displays the following table.convert double to int.

a	b	pow(a,b)
1	2	1
2	3	8
3	4	81
4	5	1024
5	6	15625

下面是参考答案代码:

public class PrintPowTableQuestion18 {
	public static void main(String[] args) {
		int a,b,PowerResult;

		System.out.println("a    b   pow(a,b)");
		
		a = 1;b = 2;PowerResult = (int)Math.pow(a,b);
		System.out.println(a + "    " + b + "   " + PowerResult);
		
		a = 2;b = 3;PowerResult = (int)Math.pow(a,b);
		System.out.println(a + "    " + b + "   " + PowerResult);
		
		a = 3;b = 4;PowerResult = (int)Math.pow(a,b);
		System.out.println(a + "    " + b + "   " + PowerResult);
		
		a = 4;b = 5;PowerResult = (int)Math.pow(a,b);
		System.out.println(a + "    " + b + "   " + PowerResult);
		
		a = 5;b = 6;PowerResult = (int)Math.pow(a,b);
		System.out.println(a + "    " + b + "   " + PowerResult);
	}
}

运行效果：

注：编写程序要养成良好习惯
如：1.文件名要用英文，具体一点
2.注释要英文
3.变量命名要具体，不要抽象（如:a,b,c等等），形式要驼峰化
4.整体书写风格要统一（不要这里是驼峰，那里是下划线，这里的逻辑段落空三行，那里相同的逻辑段落空5行等等）
