allocates only one memory at a time.Static-decorated blocks of code are called Block blocks, which are usually used for program optimization. Code in a static code block executes only once when the entire class is loaded. Static code blocks can have more than one, and if there are multiple, execute sequentially in order.Inside C + +, Static is released by the system at the end of the programThe role of 38.Final in JavaFinal可以修饰类，修饰方法，修饰变量。修饰的类叫最终类。该类不能被继承。修饰的方法不能被重写。修饰的变量叫常量，常量必须初始化，一旦初始化后，常量的值

put into the buffer, in which case it created two objects. As to whether the string class inherits, the answer is no, because the string default final decoration is not inheritable . 1 2. The difference between string and StringBufferThe Java platform provides two classes: string and StringBuffer, which can store and manipulate strings, which are character data that contain multiple characters.

then the bytes are written to the output stream. Read, the first read is the byte, but we want to display it as a character, we need to convert the bytes into characters. Because of this wide range of requirements, Java specifically provides a character stream wrapper class.The underlying device always accepts only byte data, and sometimes writes a string to the underlying device, which needs to be converted to bytes and then written. The character s

Because the "Kvill" in S0 and S1 in the example are string constants, they are determined at compile time, so s0==s1 is true, and "kv" and "ill" are also string constants, and when a string is concatenated by multiple string constants, it is itself a string constant. So S2 is also parsed as a string constant at compil
