What are the implicit conversion types in java

Java implicit conversion types include automatic widening conversion, string to basic data type conversion, automatic boxing conversion, automatic boxing conversion, etc. Detailed introduction: 1. Automatic widening conversion: When the range of one data type is smaller than another data type, Java will automatically convert the small range data type into a large range data type. For example, convert a byte type (byte) to a short integer type (short), integer type (int), long integer type (long), floating point type or double precision floating point type; 2. String to basic data Type conversion and so on.

In Java, there are the following common implicit type conversions:

Automatic widening conversion (Widening Conversion): When the range of one data type is smaller than another data type, Java will Automatically convert a small range of data types to a large range of data types. For example, convert a byte type to a short, int, long, float, or double.

String to basic data type conversion: Java can convert string types to basic data types, such as converting string types to integers (int), long integers (long), and floating point types. (float) or double precision floating point type (double), etc.

Autoboxing: The autoboxing function in Java can automatically convert basic data types into corresponding packaging class types. For example, the int type is automatically converted to the Integer type.

Implicit conversion of array types: In Java, an array of small range data types can be implicitly converted to an array of large range data types. For example, convert a byte array to an integer array.

It should be noted that implicit type conversion can only be performed when the type range allows it, otherwise it will cause compilation errors or runtime exceptions. When performing type conversions, attention should be paid to the range and precision of data types to avoid data loss or unexpected results. At the same time, explicit type conversion is also a more explicit way that can be used when needed.
