Ubuntu default System configuration file location/usr/share/byobu/profiles/tmux From The PC is connected to the VPS via Putty and has some minor problems when using the Tmux installed on the VPS. The main reason is that Putty is a terminal emulator that differs from a real terminal and requires some extra setup. Here are some of the problems encountered and provide solutions. Before you begin, introduce a method to view the control sequence of the key, which is used later. Perform: Cat >/dev/nul

interest calculation; 2. Simple interest calculation; 3. Investment; 4. Exit the system. The first three functions used three functions: A (); B (); C (). The method of implementation is probably the same, all through the input of relevant information, in the formula calculation. The main function, main (), uses the Swich () statement to select the function that invokes the function. When entering a non-1~4 integer, there is a reminder to "re-enter".

, encountered a bottleneck will be selected design mode. So what's the use of it?The essence of the simple factory pattern is that a factory class dynamically determines which product classes (these product classes inherit from a parent class or interface) should be created and returned based on the parameters passed in.So that means:1, there is a known product class2, you can not exactly know which product class to compile3. Need to decide which product class to create at run time4, the product

statement must be preceded by a break is this: This allows you to jump out of a switch immediately after finding a qualifying case to speed up execution.) It doesn't look right now. ） You can understand that switch will jump to the first matching case to continue execution, depending on the condition.The case is just a tag for switch jumps, and does not partition the block. So: Even if more than one case matches a switch, it will only jump to the first matching case. If it does not b

need to add it. Also for readability, to prevent others from reading your code when you forget to add. Adding the default branch is a good habit that can be used to catch exceptions. This approach requires that both switch and case must be constants and do not allow variables. Both switch and else if can be multiplexed, comparing the two: The switch code is more streamlined, and in many cases it is more efficient than else if, for example, the

(Testscore >= 70) {Grade = ' C ';}else if (Testscore >= 60) {Grade = ' D ';}else {Grade = ' F ';}System.out.println ("grade is" + grade);}}The output is C.You may notice that the value of testscore satisfies more than one expression in a mixed statement: 79>70;79>60. But when a condition is met, the corresponding statement executes (grade = ' C '), and the remaining conditional statement is not executed.Switch statementUnlike the If-then and IF-THEN-ELSE statements, a switch statement can have
