Webb6 okt. 2024 · Initializing a Primitive boolean Array In Java, a primitive variable has a default value. For example, a primitive int variable's default value is 0, and a primitive boolean variable will hold false by default. Therefore, if we want to initialize a boolean array with all false, we can simply create the array without setting the values. WebbInitialization of 2D Array in C In the 1D array, we don't need to specify the size of the array if the declaration and initialization are being done simultaneously. However, this will not work with 2D arrays. We will have to define at least the second dimension of the array.
