计算某一个字符串中的大小写与其它字符

public class Test {
public static void main(String[] args) {
String s = "AaaaABBBBcc^%adfsfdCCOOkk99876_haHA";
int lCount = 0;
int uCount = 0;
int eCount = 0;
for(int i=0;i<s.length();i++){
char c = s.charAt(i);
if(c >='a' && c <='z'){
lCount++;
}else if(c >='A' && c <='Z'){
uCount++;
}else{
eCount++;
}
}
System.out.println(lCount + " " + uCount + " " + eCount);

}
}
