Answer:
Here is a Java function that takes two integer parameters and uses reference parameters to exchange their values if the first parameter is greater than the second parameter:
public void exchangeValues(int[] params) {
// check if the first parameter is greater than the second parameter
if (params[0] > params[1]) {
// swap the values of the two parameters
int temp = params[0];
params[0] = params[1];
params[1] = temp;
}
}
To use this function, you can pass an array of two integers as the argument, like this:
int[] params = {5, 3};
exchangeValues(params);
// after calling the function, the array should be [3, 5]
If the first parameter is not greater than the second parameter, the function will not exchange their values. For example, if you call the function with the following array:
int[] params = {3, 5};
exchangeValues(params);
// after calling the function, the array should be [3, 5]
The values of the parameters will remain unchanged because the first parameter (3) is not greater than the second parameter (5).
