So I was trying to return the max value within an type "T" array list and got an error while using compareTo. This is the full code.
package myUtil;
public class SimpleListAry<T extends java.lang.Comparable<T>> extends java.lang.Object implements SimpleList<T> {
private T[] myList;
private int size;
public SimpleListAry(){
myList = (T[])new Comparable[10];
}
public SimpleListAry(int capacity){
if (capacity <= 0){
throw new IllegalArgumentException();
}
myList = (T[]) new Object [capacity];
}
@Override
public int size() {
size = myList.length;
return size;
}
@Override
public T get(int i) {
return myList[i];
}
@Override
public T set(int i, T item) {
return myList[i] = item;
}
@Override
public int indexOf(Object item) {
for (int i = 0; i < size; i++){
if (get(i).equals(item)){
return i;
}
}
return -1;
}
@Override
public void add(int at, T item) {
if (at < 0 || at > size)
throw new ArrayIndexOutOfBoundsException(at);
for (int i = size; i > at; i--){
myList[i] = myList [i-1];
}
// myList[at] = item;
size++;
}
@Override
public T remove(int at) {
if (at < 0 || at >= size)
throw new ArrayIndexOutOfBoundsException(at);
T item = myList[at];
for (int i = at; i<size-1; i++)
myList[i] = myList[i+1];
size--;
return item;
}
@Override
public T max() {
T max = myList[0];
for (int i = 1; i < myList.length; i++){
if(myList[i].compareTo(max) == 1)
max = myList[i];
}
return max;
}
@Override
public T min() {
T min = myList[0];
for (int i = 1; i < size -1; i++){
if (myList[i].compareTo(min) == -1)
min = myList[i];
}
return min;
}
}
and the error is at Public T max():
public T max() {
T max = myList[0];
for (int i = 1; i < myList.length; i++){
if(myList[i].compareTo(max) == 1)
max = myList[i];
}
return max;
}
I also tried using ">" to compare them but that was not working either. It may be because of the data type but there's no error in the IDE only when I attempt to run it and it points directly to this line in T max(){
if(myList[i].compareTo(max) == 1)
