public static void main(String[] args) {
// 输入3科成绩，然后把三科成绩输出，成绩为整数形式。
Scanner s=new Scanner(System.in);
int[] score=new int[3];
for (int i = 0; i < score.length; i++) {
score[i]=s.nextInt(); }
for (int i = 0; i < score.length-1; i++) {
System.out.print("score"+(i+1)+"="+score[i]+",");
}
System.out.print("score"+3+"="+score[2]);
}
用for循环遍历数组
