2，编写程序，将一个整数倒排过来，例如：给定整数：4982，得到的结果：2894。(java程序实现)

public class Test {
public static void main(String[] args) {
int a = 4982;
StringBuffer aa = new StringBuffer(a+"");
a = Integer.parseInt(aa.reverse().toString());
System.out.println(a);
}
}

public class Reverse {
//数字倒序输出
public static long reverse(long src){
long rs = 0;
do{
rs=rs*10+src%10;
src/=10;
}
while(src>0);
return rs;
}
public static void main(String[] args) {
int i =1067805730;
System.out.println(reverse(i));
}
}

public class Test {
public static void main(String[] args) {
int[] i = { 4, 9, 8, 2 };
int m = i.length;
while (m > 0) {
System.out.println(i[m - 1]);
m = m - 1;

}

}

}

public class numx
{
public static void main(String args[])
{
int a,b,c,d,f;
a=4982;
b=4982/1000;
