类型转换 由于Java是强类型语言，所以要进行有些运算的时候，需要用到类型转换 类型转换： byte,short,char--->int--->long--->float--->double （低--------------------------------------------------高） 运算中，不同类型的数据先转换成同一类型，然后进行运算 强制转换：（类型）变量名
package base;public class Day06 { public static void main(String[] args) { //操作比较大的时候，注意溢出问题 //JDK7新特性，数字之间可以用下划线分割 int money =10_0000_0000; int years =20; int total =money*years;//-1474836480，计算的时候溢出了 l
/*1. 不能对布尔值进行转换2.不能吧对象类型转换成不相干的类型3.在把高容量转换到低容量的时候需要强制转换4.转换的时候可能存在内存溢出，或者精度问题（就是小数的时候转成整数int） */System.out.println((int)23.4);System.out.println((int)23.56);System.out.println("=========

一.强制转换 (你想要转换的类型)变量名 高--低 int i = 128; System.out.println((short)i); 二.自动转换 低--高 int n = 10; double s = n; System.out.println(s); //10.0 三.拓展 操作较大的数的时候，注意溢出问题 JDK7新特性，数字之间可以用下
int i = 128; double b = 1; System.out.printin(i); sout(b); 强制转换 高容量到低容量 自动转换 低到高 注意点： 1.不能转换布尔值 2.不能把对象类型转换为不相干类型 3.在高容量转换为低容量时是强制转换 4.转换时可能出现内存溢出或精度问题 int money = 10_0000_0000; int yea

[定义]： golang的方法(Method)是一个带有receiver的函数Function，Receiver是一个特定的struct类型，当你将函数Function附加到该receiver， 这个方法Method就能获取该receiver的属性和其他方法。 [面向对象]： golang方法Method允许你在类型上定义函数，是一个面向对象的行为代码， 这也有一
