The compound assignment operators are: + =,-=, *=,/=,%=, The simple assignment operator is =;The code is as follows:public class Example009 {public static void main (string[] args) {short x = 1;int X1 = 1;int i = 123456;x + = i;//assignment 1x1 + = i;//Assignment 2system.out.println ("x =" + x + ", x1 =" + x1);}}Output

JAVA value assignment operator and value assignment operator Assign a value to the budget operator. Simply put, assign the variable value that defines the value to the variable you just defined. For example, the score of student a is the same as that of Student B. The score of student a is 80. Based on the score of student a, the score of student B is output.

The string type is a commonly used type in the actual work, separated from the data type, string is a reference type and is a class defined in the API. So objects of type string can be created using new, such as String Name=new string ("string"), assigning the variable name to a value of "string", but string analogy other classes are somewhat special, can use ' = ' to directly assign values, such as String Name= "string", which is also assigned to the variable name, a value of "string", the two

To assign values to different variables, you must use the assign operator "=". Here "=" does not mean "equal to", but "assign value". For example: A1 = 3; This statement is used to assign integer 3 to variable a1. Make the value of variable a1 3 at this time. Let's look at the following statement: A1 = a1 + 1; As you know, this representation method won't work in mathematics, but as a value assignment statement, it is often used in future programming,

Assignment operators in JavaAn assignment operator is a symbol that specifies a numeric value for a variable or constant. If you can use "=" to assign the result of the right expression to the left operand.Common assignment operators supported by Java, as shown in the following table:650) this.width=650; "src=" http://

Question: i + = j is just the shorthand for i = i + j?Answer: not also! Look at the following program:int i = 5; long j = 8+ = j; // can be compiled and the result is correct i = i + j; // cannot compile, type conversion issuesIn fact, Java will convert i + = j to i = (int) (i + j) to execute.Typically, a compound assignment expression in the form of a E1 op= E2 is equivalent to E1 = (t) ((E1) + (E2))

All browsers of the IE series cannot tolerate such errors. 3 JSON cannot tolerate the end comma. {"Name": "zhao", "age": 12} // The correct JSON format {"name": "zhao", "age": 12 ,} // incorrect JSON format It should be noted that JSON is a common data format and has nothing to do with a specific programming language.
