In database operations, there are times when we encounter the need to implement "row-to-column", for example, a table for a weekly income statement for a store: VARCHAR (Ten) DECIMAL)Let's insert some simulation data first:INSERT intoWeek_incomeSELECT 'Monday', +UNION AllSELECT 'Tuesday', -UNION AllSELECT 'Wednesday', theUNION AllSELECT 'Thursday',4000UNION AllSELECT 'Friday', theUNION AllSELECT 'Saturday',6000UNION AllSELECT 'Sunday',7000The m

From: http://daimajishu.iteye.com/blog/1081090 The value type is the stack stored in the memory (later referred to as the stack), while the reference type variable only stores the address of the reference type variable in the stack, and its own is stored in the heap.= The operation compares whether the values of two variables are equal. For a referenced variable, it indicates whether the addresses of the two variables stored in the heap are the same, that is, whether the stack content is th

occupied by the object. If you want to compare two variables that point to the same object, it depends on whether the values in the memory corresponding to the two variables are equal, at this time, we need to use the = Operator for comparison. The equals method can be used to compare whether the content of two independent objects is the same. It is like comparing two objects with the same looks. Simply put: = The operation compares whether the values of two variables are equal. For a reference

Differences between equals and = in Java = Compare the addresses of two objects, while equals compares the content of two objects. Obviously, when equals is true, ==is not necessarily set to true; The importance of basic knowledge is expected to attract everyone's attention, including yourself. Many puzzles and questions come from the most basic knowledge. After a while, I checked the books and finally got some insights on the special object string.

My understanding: Equals compares the values of two different objects to be equal. = Is to compare whether the values of the same two objects are equal.
