ArrayIndexOutOfBoundsException
package PracticeStudent;public class PracticeStdent {
public static void main(String[] args) {
int[][] student = new int;
for(int i = 0;i<student.length;i++) {
student = new int[]{i+1};
student = (int)(Math.random()*5+1);//state:1-5
student = (int)(Math.random()*26+75);//score:75-100
}
}
}
运行后，报错：
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1
at Class/PracticeStudent.PracticeStdent.main(PracticeStdent.java:9)
求解答！ 07行改为student = new int;就好了
还有08，09行不对应该改为
student = (int)(Math.random()%5+1);//state:1-5
student = (int)(Math.random()%26+75);//score:75-100
