during development and testing. To improve performance, the assertion check is usually disabled after the software is released.

1, sequential structure: that is, follow the procedures of the relationship, in turn, execution.2. Select Branch: Use IF. else,/switch () {Case [This must be constant]:}; /If.. else if ..... .... else.. Such statements let the program switch execution in different branches.3, Loop structure: Repeat the completion function, you can use while () {} (first to judge and then execute); Do{}while (); (First execution and judgment); for (initial value; end c

(int I = 2; I Running result: Iv. Infinite Loops To use an infinite loop, change the cycle condition of the loop to true (For more information about the code format, see section 2.), But it should be noted that the cycle termination conditions (using the break keyword) must be provided within the infinite loop results; otherwise, the program will be executed without limit to form an endless loop; V. break and continue: 1. break: 1. It is used in th

the switch statement format: switch (key) {case value: statement break ;... Default: statement break;} key: represents an integer selection factor value: an integer switch can compare the results of the entire expression with each case value, if yes, execute the corresponding statement. If no yes, execute the default statement. Example 1: 9x9 multiplication table 2 Method 1: nested loop (for switch) 3 publ

not met. Break Tag Name; Continue tag name; the knowledge of these two statements indicates that a tag loop exists and a tag loop is terminated in advance. It can only be used in a loop Statement (multi-layer loop nesting, nested loops are used to jump to the outer loop.Note: When using a for loop, be sure not to forget the two ";" in (). The statement of an endless loop is for (;) {} orWhile (true ){}Note

Develop public accounts using java: Receive and passively reply to common messages (3), java public The previous article describes how to access the public account. This article describes the basic functions of the Public Account: Receiving and replying to common messages. When it comes to common messages, what is the common message defined by the public number?

11. the ancient Chinese computation book Zhang qiujian computing Sutra has a famous hundred rooster problem: Each rooster is worth 5 RMB, and each hen is worth 3 RMB, the value of three chicks is 1 RMB. I used 100 yuan to buy 100 chickens. Q: How many of the 100 chickens are there? Program Analysis: this problem needs to be solved by nested for loop. x indicates the number of Rooster, y indicates the number
