how to initialize array in java

1int[] data = {10,20,30,40,50,60,71,80,90,91};
2// or
3int[] data;
4data = new int[] {10,20,30,40,50,60,71,80,90,91};
5// or
6int[] data = new int[10];
7data = {10,20,30,40,50,60,71,80,90,91};

1int intArray[];    //declaring array
2intArray = new int[20];  // allocating memory to array
3//OR
4int[] intArray = new int[20]; // combining both statements in one

1int[] array = new int[/*size*/];
2// Works for double, char, etc.

1int[] array1 = new int[5]; //int array length 5
2String[] array2 = new String[5] //String array length 5
3double[] array3 = new double[5] // Double array length 5
4

1int[] intArray = new int[]{ 1,2,3,4,5,6,7,8,9,10 }

1int[] arr = new int[5];	 // integer array of size 5 you can also change data type
