Anyone seeing this compile error?

  • 0

    I have code below but OJ is saying a compile error. I really don't understand what is happening.

    class LFUCache {
    private int cap = 0;

    public LFUCache(int capacity) {
        this.cap = capacity;
    public int get(int key) {
        return -1;
    public void set(int key, int value) {


    Line 16: error: cannot find symbol: method put(int,int)
