What is the method for forced type conversion in Java?

In Java, you can use type casting (also known as explicit type conversion) to convert one data type to another. This is done by putting parentheses in front of the target type and placing the value to be converted inside the parentheses. Here is the method for type casting:

// 声明一个变量
double number = 3.14;
// 强制将 double 类型转换为 int 类型
int integerNumber = (int) number;

In the example above, we are converting the value of the `number` variable from type `double` to type `int`, and assigning the result to the `integerNumber` variable.

It is important to note that when performing type casting, data loss or overflow may occur. For example, converting a large integer to a smaller integer type may result in truncation and data loss. Therefore, before carrying out type casting, it is essential to carefully consider the range and precision of data types.
