spaces the default initialization value is NULL. Acquisition of the length of a two-dimensional array: The length of the two-dimensional array is obtained by arr.length, and the number of one-dimensional arrays in the two-dimensional array is obtained. Such as: int [] arr = new int[3][2]; The value of Arr.length is 3. Arr[0].length gets the length of the first one-dimensional array.

For many important reasons, the Java language is very limited in its application in real time systems. These include uncertainties inherent in the design of the Java language, such as dynamic class loading, and the uncertain performance impact of the Java Runtime Environment

The Java language is an object-oriented programming language that supports network computing. The Java language absorbs the advantages of the Smalltalk language and the C + + language,

code.Semicolon: In Java, line breaks do not represent the end of a statement, only semicolons represent the end of a statement, so it is theoretically possible to write multiple statements in a row, but this is not recommended, which can affect the readability of the code and make the code look cluttered.Curly braces: A pair of curly braces represents a block of statements that need to appear in pairs.Square brackets: Used for arrays, defining arrays
