How to assign value to array in java

Use the "=" symbol to assign values ​​to the array

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

Use loops to assign values ​​to the array

The example is:

 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);
         }

Use loop traversal to assign values ​​to the array and output the array

The example is:

 int[ ] arr={1,3,6,5,6,7,84,55,5};  for (int num:arr) {
      System.out.println(num);
  }
