以下是一个使用for循环计算数组元素总和的示例: publicclassArraySum{publicstaticvoidmain(String[]args){int[]numbers={1,2,3,4,5};intsum=0;for(inti=0;i<numbers.length;i++){sum+=numbers[i];}System.out.println("数组元素总和: "+sum);}} 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. ...
用for循环遍历数组(array)的例子: 在这里,我们使用for循环遍历和显示数组里面的每个元素。 1 2 3 4 5 6 7 8 9 classForLoopExample3 { publicstaticvoidmain(String args[]){ intarr[]={2,11,45,9}; //i starts with 0 as array index starts with 0 too for(inti=0; i<arr.length; i++){ ...
Note that all expressions in thefor-loopare optional. In case, we do not provide theterminationexpression, we must terminate the loop inside the statements else it can result in aninfinite loop. 2. Java For-loop Example In the following program, we are iterating over an array ofintvalues....
Series of values. Thefor-eachloop is used to access each successive value in a collection of values. Arrays and Collections. It's commonly used to iterate over an array or a Collections class (eg, ArrayList). Iterable<E>. It can also iterate over anything that implements theIterable<E>int...
publicclassArrayIterationExample{publicstaticvoidmain(String[]args){int[]numbers={10,20,30,40,50};for(int i=0;i<numbers.length;i++){System.out.println("Element at index "+i+": "+numbers[i]);}}} This example demonstrates iterating over an array. The loop iterates through thenumbersar...
When you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop:SyntaxGet your own Java Server for (statement 1; statement 2; statement 3) { // code block to be executed }...
Java for-each循环(遍历循环) 在Java中,for循环的另一种语法可用于Java数组和Java集合(称为遍历循环)。例如, for (int a : array) { System.out.println(a); } 要了解更多信息,请访问:Java 遍历循环 Java 方法重载Java switch语句Copyright ©2021 菜鸟教程 cainiaojc.com...
