1. Java selection structure
1. if (condition)...else structure
When the condition == true, execute the statement under if. Otherwise, execute the statement under else
2, if (condition 1)...else if (condition 2)...else structure (relevant video tutorial recommendation: java video tutorial )
When condition 1==true, execute the statement under if (condition 1); when condition n==true, execute the statement under else if (condition n); when neither is satisfied Execute the statement under else
3. switch (operation statement)...case value structure
When the result of the operation statement == the value of case, enter Corresponding case execution statement
default: No matter which case is entered, as long as there is no break, default will be entered in the end
break: Jump out of the current selection structure. If there is a break in the case entered, then directly Jump out of switch
3.1, without default and no break
3.2, with default and no break
3.3. There is default and break
## 2. Java loop structure1. While (conditional) loop, suitable for situations where the number of loops is unknown but the entry is known The condition of the loop is When the condition == true, enter the loop 2. do...while (condition) loop, suitable for situations where the number of loops is unknown , but knowing the condition to stop the loop is The statement in the value loop, until the condition == false, jump out of the loop 3. for loop , suitable for situations where the number of loops is knownFormat: for (define a variable; condition; operation statement) {statement to be executed for each loop} 3. return, break, continuereturn: jump out of the current method and return data (optional) break: jump out of the current logical structure continue: jump out In this loop, execute the next loop (the code after continue in this loop will not be executed) Recommended related articles and tutorials:The above is the detailed content of Detailed explanation of java logic control statement examples.
