1. Direct assignment
arr[0]=1; 0代表的是数组的第1个元素 ,元素下标为0 arr[1]=1; 1代表的是数组的第2个元素 ,元素下标为1
2. Use for loop assignment
int[ ] arr=new int[5];
for (int i = 0; i < arr.length; i++) {
System.out.println("数组第"+(i+1)+"个值为"+i);
}Result:
3. Use loop traversal to assign values to the array
int[ ] arr={1,3,6,5,6,7,84,55,5};
for (int num:arr) {
System.out.println(num);
}Result:
