3 nested for loops java

beyondThe value range of a byte, you must use a double-byte representation in the Java language using Unicodeencoding, which can store 65,535 characters, so the Java character type is defined as double-byte, which is also fullThe storage needs of Chinese characters are sufficient.Char type variables can store Chinese characters because Java is encoded in Unicode

purposes. If a nested class needs to be visible outside of a single method, or it is too long, it is not suitable to be placed inside a method, so the Member class should be used. If each instance of the member class needs a reference pointing to its peripheral instance, the member class is made non-static; otherwise, it is made static. Assume that a nested class is inside a method. If you only need to cre

Java collection classesThe collection classes for Java are located in the Java.util package, where the Java collection holds references to objects, not to the object itself.There are three main types of Java collections:1.Set (SET): Objects in the collection are not sorted in a particular way, and there are no duplicat

concurrently by multiple threads, but cannot be modified by any thread. Shared read-only objects include immutable objects and fact-invariant objects.　　thread -safe sharing: Thread-safe objects are synchronized internally, so that threads can be accessed through the public interface of an object without further synchronization.　　protected Object : The protected object can only be accessed by holding a specific lock. Protection objects include objects encapsulated in other thread-safe objects, a

Ready state (Runnable): After the thread object is created, other threads call the object's start () method. The state of the thread is located in a pool of running threads that becomes operational and waits for the CPU to be used.3. Running state (Running): The ready state of the thread g

In practical programming, it is sometimes necessary to jump out of a loop when a conditional statement is matched. In Java, it is controlled by the break and continue statements."Break" statementThe "break" statement is used to end the loop, that is, all loops behind it are no longer executed.Example: Calculate the result of a 1+2+3+4......+100.public class examp
