compareTo在Java中做什么？
compareTo()Java中的方法按字典顺序比较两个字符串。
示例
public class Test {
public static void main(String args[]) {
String str1 = "Strings are immutable";
String str2 = new String("Strings are immutable");
String str3 = new String("Integers are not immutable");
int result = str1.compareTo( str2 );
System.out.println(result);
result = str2.compareTo( str3 );
System.out.println(result);
}
}输出结果
