Widening casting is done automatically when passing a smaller size type to a larger size type: ExampleGet your own Java Server publicclassMain{publicstaticvoidmain(String[]args){intmyInt=9;doublemyDouble=myInt;// Automatic casting: int to doubleSystem.out.println(myInt);// Outputs 9System.out...
隐式casting(from small to big) byte a = 111; int b = a; 显式casting(from big to small) int a = 1010; byte b = (byte)a; 注意: 从大到小必须强转! 一道著名的公司面试题如下,以下程序有何问题? public class Test { public static void main(String[] args) { short s1 = 1; s1 = ...

Java是强类型语言,不是所有的类型都可以随便自动转换。把 int 类型的值赋给 long 类型的变量,总是可行的。但是,反过来,将 long 类型 赋值给 int 类型,你必须使用强制类型转换。Java 的类型转换分两种:自动类型转换– 没有任何的表现形式,Java自动处理强制类型转换– 需要使用类型转换语法Java的自动转 java type...
请注意,当Java检测到类型转换可能会导致数据丢失(较大的数据类型转换为较小的数据类型)时,会给出type-mismatch error并明确要求进行type casting (例如,将“ int”分配为“ short”)。 它有助于检测和解决意外的数据丢失分配。 2.2. Non-primitive Data Types ...
double i = 100.7; int j = (int) i; In above example a double variable(8 Byte) converted into integer variable (4 Byte) . The casting happened from a higher data type to a lower data type, so can result in loss of information. ...
