What is the for statement in java
Explanation
1. The for keyword means when..., it is a commonly used loop sentence in actual development. Its grammatical form is slightly more complicated than the previous loop sentence, but After getting familiar with it, I found that its grammatical arrangement is relatively orderly, and loop control and loop body are clearly separated.
Execution process
2. Start the initial statement. Determine the loop condition. If the loop condition is false, end the loop, otherwise the next step will be executed. Execute the loop body. Execute the iteration statement. Skip to step 2 and repeat the execution. Note that each statement in the for statement can be empty, and the initial statement is only executed once when executing the for statement.
Example
int sum = 0;
for (int i = 1; i <= 100; i++) {
sum += i;
}
System.out.println("1累加到100的结果是:" + sum);The above is the detailed content of What is the for statement in java. For more information, please follow other related articles on the PHP Chinese website!

Exploring Common Java Design Patterns with Examples
Aug 17, 2025 am 11:54 AM
The Java design pattern is a reusable solution to common software design problems. 1. The Singleton mode ensures that there is only one instance of a class, which is suitable for database connection pooling or configuration management; 2. The Factory mode decouples object creation, and objects such as payment methods are generated through factory classes; 3. The Observer mode automatically notifies dependent objects, suitable for event-driven systems such as weather updates; 4. The dynamic switching algorithm of Strategy mode such as sorting strategies improves code flexibility. These patterns improve code maintainability and scalability but should avoid overuse.

Java Cryptography Architecture (JCA) for Secure Coding
Aug 23, 2025 pm 01:20 PM
Understand JCA core components such as MessageDigest, Cipher, KeyGenerator, SecureRandom, Signature, KeyStore, etc., which implement algorithms through the provider mechanism; 2. Use strong algorithms and parameters such as SHA-256/SHA-512, AES (256-bit key, GCM mode), RSA (2048-bit or above) and SecureRandom; 3. Avoid hard-coded keys, use KeyStore to manage keys, and generate keys through securely derived passwords such as PBKDF2; 4. Disable ECB mode, adopt authentication encryption modes such as GCM, use unique random IVs for each encryption, and clear sensitive ones in time
