任意输入4个字母，然后把字母退后7位，最后掉转过来，这个程序应该怎么写？例如abcd就变成kjihjava就变成h}hqpublicclassE2{publicstaticvoidmain(String[]args){EasyReaderkeyboard=...

任意输入4个字母，然后把字母退后7位，最后掉转过来，这个程序应该怎么写？ 例如abcd就变成kjih java就变成h}hq

public class E2 {

public static void main(String[] args) {

EasyReader keyboard = new EasyReader();

//char a = keyboard.readChar("Type a character: ");

int a=(int)a+7;

//int a = keyboard.readInt("Type a decimal Unicode number: ");

//string1=(char) a

//char b = keyboard.readChar("Type a character: ");

int b=(int)b+7;

//int b = keyboard.readInt("Type a decimal Unicode number: ");

//string2=(char) b

//char c = keyboard.readChar("Type a character: ");

int c=(int)c+7;

//int c = keyboard.readInt("Type a decimal Unicode number: ");

//string3=(char) c

//char d = keyboard.readChar("Type a character: ");

int d=(int)d+7;

//int d = keyboard.readInt("Type a decimal Unicode number: ");

//string4=(char) 4;

//string5=string4+string3+string2+string1

System.out.println(string5);

}

}

这个编程可以不？
