JAVA简单实现不区分大小写以及空格比较字符串

import java.io.*;import java.util.*;public class Test {public static void main(String[] ags) {String s1 = "ab c k";String s2 = "ABCK";String s3 = "abkc"System.out.println(compare(s1, s2));System.out.println(compare(s1, s3));}static boolean compare(String str1, String str2) {String s1 = str1.replace(" ", "");String s2 = str2.replace(" ", "");return s1.equalsIgnoreCase(s2);}}

利用String类很简单的就实现了
