我正在為實(shí)驗(yàn)室編寫一個(gè)調(diào)整大小的函數(shù)，但我不斷收到錯(cuò)誤線程“main”中的異常 java.lang.OutOfMemoryError：Java 堆空間private E[] a, b; // holds the itemsprivate int N; // number of items in stack// create an empty stack with given capacitypublic RArrayStack() { a = (E[]) new Object[8]; N = 0;}public boolean isEmpty() { return N == 0;}public boolean isFull() { return N == a.length;}public void push(E item) { if (!this.isFull()) { a[N++] = item; } else { this.resize(); }}public E pop() { return a[--N];}public E peek() { return a[N - 1];}public E[] resize(){ b = (E[]) new Object[a.length*2]; for (int i = 0; i < a.length ; i++) { b[i] = a[i]; } a = b; return resize();}

在你的resize()函數(shù)中：
public E[] resize(){
b = (E[]) new Object[a.length*2];
for (int i = 0; i < a.length ; i++) {
b[i] = a[i];
}
a = b;
return resize();
}
您無(wú)條件地調(diào)用resize()return，這意味著該方法將遞歸，直到您嘗試為 new 分配足夠的內(nèi)存為止b。而不是return resize()，你想返回a
