After the equals sign, you need the Java keyword new, and then your data type again. After the data type come a pair of square brackets. In between the square brackets you need the size of the array. The size is how many positions the array should hold.
So we are telling Java to set up an array with 6 positions in it. After this line is executed, Java will assign default values for the array. Because we've set up an integer array, the default values for all 6 positions will be zero 0. Here, a value of 10 is being assigned to position 0 in the array called aryNums. Again, the square brackets are used to refer to each position. If you want to assign a value of 14 to array position 1, the code would be this:.
Don't forget, because arrays start at 0, the third position in an array has the index number 2. This method of setting up an array uses curly brackets after the equals sign. In between the curly brackets, you type out the values that the array will hold. The first value will then be position 0, the second value position 1, and so on. Note that you still need the square brackets after int, but not the new keyword, or the repetition of the data type and square brackets.
But this is just for data types of int values, string, and char values. Otherwise, you need the new keyword. Last Updated : 10 Jun, Attention reader!
