按照你的要求编写的Java程序如下
import java.util.Scanner;
public class S{
public static void main(String[] args){
int n=5;
int[] a=new int[n];
System.out.print("请输入"+n+"个正整数:");
Scanner sc=new Scanner(System.in);
for(int i=0;in;i++){
a[i]=sc.nextInt();
}
System.out.print("其中的偶数为:");
for(int i=0;in;i++){
if(a[i]%2==0){
System.out.print(a[i]+" ");
}
}
}
}

public static void main(String[] args) {
byte a =1;
short b=1;
int c = 1;
long d = 1l;
float e=1f;

System.out.println("byte a ="+a);
System.out.println("short b="+b);
System.out.println("int c ="+c);
System.out.println("long d ="+d);

System.out.println("int x="+x);
System.out.println("long y"+y);
System.out.println("boolean z"+z);
}
