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);
}
}
