有一个字符串String str="qeirqndfadsrweqewrqewr",从键盘输入任意多个字符，例如输入：a b e，判断str中是否完全包含a b e三个字符（即字符串中既要包含a，也要包含b，还要包含e），如果完全包含，输出success，否则输出failed

//jdk1.6.0.12下编译通过

package proc;

import java.util.Scanner;

public class ScanerChar {

	private static final String str="qeirqndfadsrweqewrqewr";   
    public static void main(String[] args) {   
        Scanner scanner = new Scanner(System.in);   
        String ss = scanner.nextLine();   
        int flag = 0;   
        int strvoid = 0;
        for(int i = 0;i < ss.length();i++){   
            char c = ss.charAt(i);   
            if(str.indexOf(String.valueOf(c).toLowerCase()) != -1 ){   
                flag++;   
            }  
            if (" ".equals(String.valueOf(c).toLowerCase())){
            	strvoid++;
            }
        }   
        System.out.println("flag="+flag);
        System.out.println("strvoid="+strvoid);
        if(flag+strvoid == ss.length()){   
            System.out.println("SUCCESS");   
        }else{   
            System.out.println("FAIL");   
        }   
    }   

}
