步骤1:创建新数组 首先,我们定义一个方法push,并在方法内创建一个新的数组。 publicclassArrayUtils{// 定义一个push方法,用于添加元素到数组末尾publicstaticint[]push(int[]originalArray,intnewElement){// 创建一个新的数组,比原数组大1int[]newArray=newint[originalArray.length+1];// 原数组长度+1 1. ...
下面是一个使用Java代码实现数组push操作的示例: publicclassArrayPushExample{publicstaticvoidmain(String[]args){// 创建一个初始长度为3的数组int[]array=newint[3];// 添加元素到数组中array=push(array,10);array=push(array,20);array=push(array,30);// 输出数组元素for(inti=0;i<array.length;i++...

vararr1=newArray();vararr2=[];vararr3=[1,2,3]; 添加元素 - push 向数组的末尾添加一个或更多元素,并返回新的长度。 代码语言:javascript 复制 arr1.push(1);arr1.push('aaa','bbb'); 与push相反的方法:unshift 向数组的开头添加一个或更多元素,并返回新的长度。 取出元素 - pop 删除并返回数组...
push() Adds new elements to the end of an array, and returns the new length reduce() Reduce the values of an array to a single value (going left-to-right) reduceRight() Reduce the values of an array to a single value (going right-to-left) reverse() Reverses the order of the eleme...
console.log(languages); // [ 'JavaScript', 'Python', 'Java', 'Lua', 'C++' ] console.log(count); // 5 var priceList = [12, 21, 35]; var count1 = priceList.push(44, 10, 1.6); console.log(priceList); // [ 12, 21, 35, 44, 10, 1.6 ] console.log(count1); // 6 ...
push() 向数组的末尾添加一个或更多元素,并返回新的长度。 var numbers = new Array(1, 4, 9); var length = numbers.push(10); console.log("new numbers is : " + numbers ); // 1,4,9,10 length = numbers.push(20); console.log("new numbers is : " + numbers ); // 1,4,9,10,...

用法: arr.push(arg1,arg_2, ... ); 返回值 : 返回修改后的数组长度。 是否改变原数组 : 是 vararr=[1,2,3,4,5,6];varnew_arr=arr.push(7,8,9);console.log(arr);// [ 1, 2, 3, 4, 5, 6, 7, 8, 9 ]console.log(new_arr);// 9 ...
