帮忙编2个简单的JAVA 程序。非常急

第一个:

import java.util.Scanner;

public class Test2 {
public static void main(String[] args) {
System.out.println("请输入一个整数x:");
Scanner sc = new Scanner(System.in);
int x = sc.nextInt();
int y = 0;
if (x < 1) {
y = x;
} else if (1 <= x && x < 10) {
y = 2 * x - 1;
} else if (x >= 10) {
y = 3 * x - 11;
}
System.out.println("y值是:" + y);
}
}

================================================================

第二个:
public class Test1 {
public static void main(String[] args) {
System.out.print("既是2的倍数,又是3的倍数的是:");
for (int i = 1; i < 100; i++) {
if(i%2==0 && i%3==0){
System.out.print(" "+ i);
}
}
}
}
