不能从double双精度类型转换到float单精度类型。 错误的原因: 浮点常量的默认类型是double,改成float类型后面要加F。 正确的代码: public class bbb { public static void main(String[] args) { float f1=1.65F;//浮点常量的默认类型是double,改成float类型后面要加F。 System.out.println(f1); } } 1. 2...

1 Java 并非“严格”的“面向对象”编程语言 与C# 的规则“一切数据类型均继承自 System.Object”不同,Java 定义了一组基础数据类型,它们与 Object 数据类型没有继承关系。它们包括 int, double , boolean 等等。 如果需要遵循“严格”的“面向对象”,可以使用它们的封装类(Wrapper Class)。下面是几个例子。
