The char array will be initialized to '\u0000' when you allocate it. All arrays in Java are initialized to the default value for the type. This means that arrays of ints are initialised to 0, arrays of booleans are initialised to false and arrays of reference types are initialised to null. Initializing Java char Array.Today we will look into Two-dimensional array in java. Initialize it. Use a frequency array to store the frequency of each character. Convert the string to a character array. Use two for loops to calculate the frequency of each element. Use the first for loop to iterate through each character of the array. Initialize each element of the frequency array as 1. Initializing an array. Declaring an array does not initialize it. In order to store values in the array, we must initialize it first, the syntax of which is as follows: datatype [ ] arrayName = new datatype [size]; There are a few different ways to initialize an array. Look at the following examples to get a better idea about array initialization. The first line in the loop is to initialize the char array. It uses the charAt () method to copy the content of the string into the array, and it returns the character at a particular index. The function throws an IndexOutOfBoundException when the index ranges out of the length of the given string. At last, the sequence gets printed in the loop. Answer (1 of 3): Character arrays are often very closely related to strings in many languages.
