java每日一题收藏
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"); } } }
