楼主是要排序原来的char数组还是要从控制台从新输入一个新数组？应该是后面的吧！

Scanner input = new Scanner(System.in);
char[] letter = new char[7];
int i;
for (i = 0; i < letter.length; i++) {
letter[i] = input.nextLine().charAt(0);
}
System.out.println("原字符序号：");
for (i = 0; i < letter.length; i++) {
System.out.println(letter[i] + "");
}
Arrays.sort(letter);
System.out.println("升序排序后：");
for (i = 0; i < letter.length; i++) {
System.out.println(letter[i] + "");
}

Arrays.sort(letter);
letter[i]=input.nextInt();
你每次都将数据排序一次，然后输入代替原来的。。。想干什么

[JavaNet的牛肉粉丝]

Scanner input=new Scanner(System.in);
char[] letter=new char[]{'a','c','b','e','p','f','z'};
System.out.println("原字符序号：");

int i;
for(i=0;i<letter.length;i++){
Arrays.sort(letter);
letter[i]=(char)input.nextInt();
}
System.out.println("升序排序后：");
for(i=0;i<letter.length;i++){
System.out.println(letter[i]+"");
}

会死循环
