publicclassIncrementByTwo{publicstaticvoidmain(String[]args){for(inti=0;i<10;i+=2){System.out.println("当前的值是:"+i);}}} 1. 2. 3. 4. 5. 6. 7. 在上面的代码中,我们初始化变量i的值为0,然后设置条件i < 10,每次循环结束后通过i += 2来更新i的值。循环体中打印出当前的值。 当执...
since we are incrementing the value of i, it would always be greater than 1 (the Boolean expression: i>1) so it would never return false. This would eventually lead to the infinite loop condition. Thus it is important to see the co-ordination...
For example, we can rewrite the previous example as below. We have taken out thecounterinitialization before the loop. We have moved the counter increment and the termination statements inside the loop body. The statements are the same as the previous version. int[]array=newint[]{0,1,2,3,...
for(初始化initialization; 循环条件condition; 递增/递减increment/decrement) { statement(s); } for循环的执行流程 当程序在运行的时候,解释器一直在跟踪要执行的语句,我们称之为控制流,或者程序的执行流程。 第一步:在for循环中,首先进行初始化,在整个for循环中,初始化部分的语句只在开始的时候执行一次。 第二...
Let’s start looking at the for loop evolution over different java releases. 让我们开始研究不同Java版本上的for循环演变。 (Basic for loop) Main elements of, “for” loop are initialization, termination condition, and loop increment logic. Let’s see a sample here: ...
Expression 3 can also be omitted (like when you increment your values inside the loop): Example leti =0; letlen = cars.length; lettext =""; for(; i < len; ) { text += cars[i] +""; i++; } Try it Yourself » Loop

3. for Loopin C It also executes the code until the condition is false. In this, three parameters are given: Initialization Condition Increment/Decrement Syntax: for (initialization; condition; increment/decrement) { // Code statements to be executed } It is used ...
for (initialization;termination;increment) {statement(s)} When using this version of theforstatement, keep in mind that: Theinitializationexpression initializes the loop; it's executed once, as the loop begins. When theterminationexpression evaluates tofalse, the loop terminates. ...
Program 2: Reverse a number using for Loop The logic in this program is same as above program, here we are usingfor loopinstead of while loop. As you can see, in this program we have not used the initialization andincrement/decrementsection of for loop because we have already initialized ...
