Swap Two Numbers in Java Without Using a Temporary Variable Previously, we observed the use of a temporary variable to swap two numbers in Java. Let’s now examine a Java method for swapping two numbers without the use of a temporary variable. Using Arithmetic Addition and Subtraction We learn...
Swaps the elements at the specified positions in the specified list. (If the specified positions are equal, invoking this method leaves the list unchanged.) Parameters: list - The list in which to swap elements. i - the index of one element to be swapped. j - the index of the other el...
在C语言中,可以使用传递指针的方式实现有效的Swap(),原因在于C提供了直接的取地址和引用地址的操作。Java则没有提供直接操作内存地址的操作,因此不容易实现形如swap(Object x,Object y)的方法。 Solution 在Java中实现交换,经常借助于数组,一般形式为 public static void exec(Object[] a, int x, int y); 1....

Swapping in Java:The swapping just above using reference parameters in C doesn't work in Java, since Java doesn't have these kind of parameters, but often an application really only needs to swap two values in an array. In this case one can pass the array and the two indexes to swap ...
