if-else-if statement is used when we need to check multiple conditions. In this statement we have only one “if” and one “else”, however we can have multiple “else if”. It is also known asif else if ladder.
There are four types of if statement in Java: Java中有四种类型的if语句: if statement 如果声明 if-else statement if-else语句 if-else-if ladder if-else-if梯子 nested if statement 嵌套if语句 (if Statement) The if statement is a single conditional based statement that executes only if the pro...
4. If the statement in Line 33 of Figure 1 is enabled (where it is currently commented out) and the refactoring for AtomicIn- teger can be attempted, this refactoring should not rewrite any code fragment in that case. This is because the synchro- nized block using the lockObject in Line...
Program 3: Reverse a number using recursion Here we are usingrecursionto reverse the number. A method is called recursive method, if it calls itself and this process is called recursion. We have defined a recursive methodreverseMethod()and we are passing the input number to this method. This...
The if-else statement is the most basic way to control the flow of your code. It’s more verbose than the switch statement, but it can handle more complex conditions. Here’s an example: intnum=2;if(num==1){System.out.println('One');}elseif(num==2){System.out.println('Two');...
In this case, the simple program is now general-purpose. The user determines the variable values each time the program is run, using the INPUT statement, which prompts the user with the text enclosed within quotes. When the program is run, the screen would look as follows, with the operato...
In the above program, we are using the for loop to print the value of i in each iteration. To know how for loop works, visit Java for loop. Notice the statement, if (i > 4 && i < 9) { continue; } Here, the continue statement is executed when the value of i becomes more than...
conditions is a result of the program’s state change. That is, there will be an if-else condition inside another if-else. If, if-else, if-else-if, jump, switch-case, etc., are some of the other decision making statements in Java. Now, let us see the Nested-if Statement in ...
当一个语句写在一个阻止它执行的地方时,就会发生“Unreachable statement”错误。通常它出现在中断或返回语句之后。 for(;;){ break; ... // unreachable statement}int i=1;if(i==1) ...else ... // dead code 1. 2. 3. 4. 通常简单地移动返回语句将修复错误。阅读关于如何修复Unreachable Statement...
The break statement in Java terminates the loop immediately, and the control of the program moves to the next statement following the loop. It is almost always used with decision-making statements (Java if...else Statement). Here is the syntax of the break statement in Java: break; How bre...
