求大神帮忙,谢谢!!!!!(要Java代码)
//第一题的答案:
import java.util.Scanner;
public class test {
public static void main(String[] args)
{
System.out.println("输入购买金额:");
Scanner input=new Scanner(System.in);
double a=input.nextDouble();
System.out.println("输入顾客类型(会员或普通):");
String b=input.next();
if(b=="会员")
{
if(a=100)
{
a=a*0.8;
System.out.println("需付款:"+a);
}
else
{
System.out.println("携州需付款:"+a);
}
}
if(b=="普通")
{
if(a=200)
{
a=a*0.75;
System.out.println("需付款:"+a);
}
else
{
System.out.println("需付款:"+a);
}
}
}
}
//下面是第二题答案:
public class test {
public static void main(String[] args)
{ 陵烂
for(int i = 0; i 3; i++)
{
for(int x = i + 1; x 3; x++)
{
System.out.print(" ");
}
for(int y = 0; y (i + 1) * 2 - 1; y++)
{
System.out.print("*");
}
System.out.println();
}
尺隐漏 for(int i = 0; i 4; i++)
{
for(int x = 0; x i; x++)
{
System.out.print(" ");
}
for(int y = i; y 2 * 4 - i - 1; y++)
{
System.out.print("*");
}
System.out.println();
}
}
}
