In java

if i have this pseudo code that tries to explain how a method will work using recursion how can i turn this into working java code

// Among indexes first...last, return index of the target.
// If target is not present then return -1.
// precondition: the elements of array are in descending order.
static int find(int [] array, int first, int last, int target)
if (first > last) {
// one very short line
}
if (first == last) {
// one line, using the conditional operator
}
int mid = (first+last+1)/2;
if (target <= array[mid]) {
// one line, involving a recursive call
}
// one line, involving a recursive call
