所以运用reduce我们可以做sum,min,max,average,所以这些我们称之为针对具体应用场景的reduce,这些常用的reduce,stream api已经为我们封装了对应的方法。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 //求和 sum List<Integer> integers = Arrays.asList(1, 2, 3, 4, 5); // 没有起始值时返回为Option...

char 字符型(16个bit,也就是2字节,它不带符号!)范围是0 ~ 65535 使用Unicode表示就是:\u0000 ~ \uffff 字符要用单引号扩起来!比如 char c = '淦'; 字符其实本质也是数字,但是这些数字通过编码表进行映射,代表了不同的字符,比如字符'A'的ASCII码就是数字65,所以char类型其实可以转换为上面的整数类型。

程序定义了带可变参数的方法average(),它的功能是返回传递给该方法多个double型数的平均值。该程序调用了average()方法并为其传递三个参数,输出结果为72.0。 在可变参数的方法中还可以有一般的参数,但是可变参数必须是方法的最后一个参数。例如,下面定义的方法也是合法的: 注意:在调用带可变参数的方法时,可变参数是...
