for (int i = 0; i < my_array.length-1; i++) { for (int j = i+1; j < my_array.length; j++) { // Check if two elements are equal and not the same element. if ((my_array[i] == my_array[j]) && (i != j)) { // If a duplicate is found, print the duplicate ...
You can't access the mountain array directly. You may only access the array using aMountainArrayinterface: MountainArray.get(k)returns the element of the array at indexk(0-indexed). MountainArray.length()returns the length of the array. ...
在Java 8 之前,我们通常使用 for 循环或者增强型 for 循环来查找数组中的特定元素的索引。下面是一个使用 for 循环实现的示例代码: AI检测代码解析 publicclassArrayIndexFinder{publicstaticintfindIndex(int[]array,inttarget){for(inti=0;i<array.length;i++){if(array[i]==target){returni;}}return-1;}...
在Java中,所有的数组都有一个缺省的属性length,用于获取数组中元素的个数 数组的复制:System.arraycopy() public static void arraycopy(Object src,int srcPos,Object dest,int destPos,int length) Copies an array from the specified source array, beginning at the specified position, to the specified posit...
