Problem with instantiating generic types.

QueArr.java

package Task2;

/**

public class QueArr<T> {
    private T[] arr;
    private int first;
    private int last;
    private int length = 8;

    public QueArr(){
        arr = new T[length]; // Type parameter 'T' cannot be instatiated directly
    }
}
