First of all, the main reason for this problem is that the Javac version of the compilation conflicts with the version of the actual project compilation, so the problem is solved from these aspects:1. View the project JDK version and language level, File-->project structrue-->project2. View the level of compilation, File-->settings-->build,execution,deployment-->compiler-->java Compiler Modify the level of compilation3. For MAVEN projects you can conf

Base B = new Sub ();When a Java base class variable receives a reference to a subclass object, it is transformed upward:At this time1, variable B can be accessed by default method is still the base class itself unique public and protected method, private method is not directly accessible to the outside world, this is always the same"equivalent to base B = new Base ()"2. The Sub itself is unique and does not have a method in base (whether it is public,

. Because the new value is smaller than the original, so you must ensure that the original value of the bit after the decimal point is 0, only in this way can be set than the original small precision.Example: The original value is: 4.1235648, want to set the scale to less than 7 will be wrong, if the original value is: 4.1235000, the scale is set to less than 4 bits will be wrong, and set to 4, 5, 6, 7 are no problem, set a larger, certainly will not be wrong)Add (BigDecimal) BigDecimal the valu

the conversion from byte to char is not a widening of the basic type conversions , but rather widens and narrows the basic type conversions : Byte is first converted to int, and then int is converted to char.These seem more complex, with a rule describing the symbolic expansion behavior when converting from a narrower integer type to a wider one: if the initial numeric type is signed, the symbol expands , and if it is char, it performs 0 expansion Regardless of the type to be converted.

CompareTo method Principle: First read out the first "letter" of the string to compare, the method of comparison is the ASCII code table value (character corresponding to the decimal value), if the previous large then return 1, the back of the large return-1; This position is the same, continue to compare the next, until the last one, If all are the same, return 0;Example:int cc= "". CompareTo ("12");System.out.println (CC);int dd= "one". CompareTo ("12");System.out.println (CC);int dd= "AAA". C

Learn to program, although there are teachers taught, but more important things to self-study. This is very important.Now there are too many resources on the internet, and there is a problem: how can we learn the knowledge and master the skill in a certain time?Theoretical Contact Practice!Apply!!Online resources too much, to boldly abandon their own knowledge, do not start from beginning to end a tutorial to read, this undoubtedly wasted time.-------Recommendations1 with questions to watch the

Static variable: thread is not secure.The variable with the static keyword can only be placed in a class and cannot be placed in a method.A static variable is a class variable, located in the method area, shared for all objects, shares a portion of memory, and once the static variable is modified, the other objects are visible to the modification, so the thread is not secure. Instance variables: Singleton mode (only one object instance exists) thread is not secure, not singleton thread safe.Vari
