assignment operator expression java

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

3.4.2 Assignment operatorTable 3-9 lists these operators and their descriptions.As you can see, these operators also include VAR1 in the calculation process, the following code:Var1 + = var2;The result is the same as the following code.var1 = var1 + var2;Note: the + = operator can also be used for strings, as with the + operator.Using these operators, especially when using long variable names, makes your co

is no longer involved in the operation. So the result is x=2 y=1 (++y = = 2 Not participating in the operation) int x = 1,y = 1; if (x++==1 | ++y==1) { x = 7; } System.out.println ("x=" +x+ ", y=" +y); The result above is x=7,y=2 because | operations, regardless of the left is true false right are involved in the operation, so ++y = = 1 to participate in the operation. At this point the if condition is set to execute x = 7. int x = 1,y = 1; if (x++==1

The extended assignment operator, which is +=,-=,*=,/=,%=,=,|=,^=,code example one:BYTE a=5;　　a=a+5;Code Compile error at this time. Because, Byte,short,char in an expression is automatically converted to the int type. Therefore, the a+5 is of type int and cannot be assigned to a byte type.code example two:BYTE a=5;a+=5;There is no error in the code at this point

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 o

destroyed. Dynamically assigned object. When delete is applied to the pointer to it. When the complete expression is created, the temporary object ends. When a pointer to an object is referenced or out of scope, the Destructor will not be executed.13.1.4 Rules 3/5 If a class requires destructor, you must copy the constructor and copy the value assignment operator
