When using dom4j, we cannot obtain an element across layers. it must be obtained at one layer, which is very troublesome. Why xpath? When using dom4j, we cannot obtain an element across layers. it must be obtained at one layer, which is very troublesome.Therefore, we can use the xpath technology to access a node more conveniently, which allows us to conveniently read the specified node. Xpath is usually used in combination with dom4j, and if you want to use xpath, you need to introduce a new

Java code String STR = new string ("AAA "); How many string objects have been created in this line of code? The answer is 2, not 3. Because new string ("AAA") is equivalent to "AAA" and the original Instance Object created when it is placed in the heap, and the other is the "AAA" object in the constant pool, of cour
