a=16 b=9.5 a<b 明显错误啊 

public class HelloWorld{

    public static void main(String[] args) {

int a=16;

double b=9.5;

String str1="hello";

String str2="imooc";

System.out.println("a等于b：" + (a  == b));

System.out.println("a大于b：" + (a  > b));

System.out.println("a小于等于b：" + (a  <= b));

System.out.println("str1等于str2：" + (str1 ==  str2));

}

}
