? 第一個(gè)問(wèn)題和第二個(gè)問(wèn)題：
? //完成 main 方法
??? public static void main(String[] args) {
????? HelloWorld hello=new HelloWorld();??
???? hello.arraysScores(scores);
???? int[]scores={89,-23,64,91,119,52,73};
??? System.out.println("考試成績(jī)的前三名為:");????
? ? ?一： ? 你還沒(méi)有定義數(shù)組就已經(jīng)傳參，參數(shù)自然是找不到的，應(yīng)該吧這兩行順序顛倒
????二：加入你想輸出的效果是
????考試成績(jī)的前三名為:88 88 88 ?（假如是88）
? ?那順序應(yīng)該更改為
?System.out.println("考試成績(jī)的前三名為:"); ?
?int[]scores={89,-23,64,91,119,52,73};
hello.arraysScores(scores);
第二個(gè)問(wèn)題：
public? void arraysScores(scores){
??????? int count=0;
參數(shù)變量類(lèi)型沒(méi)有寫(xiě) ?應(yīng)改為 (int[] scores)
其他問(wèn)題能力有限暫未看出。
