In Java, an array is a collection of fixed size. Insert Element in Array. You cannot increase or decrease its size. After adding carry, make carry = 0 for the next iteration. Using Long.toString() You can use Long class toString() method to convert long to String. In the utility method, I will create a temporary array, whose size will be the addition of the length of array and number of elements to add in the array. There is no shortcut method to add elements to an array in java. If you have an array of objects while assigning values to the elements of it, you need to make sure that the objects you assign should be of the same or, a subtype of the class (which is the type of the array). In this post, we will see how to convert long to String in java. Java Program to merge two arrays into a single array. You can initialize the array by assigning values to all the elements one by one using the index − myArray [0] = 101; myArray [1] = 102; Assigning values to an array. When we assign primitive values of one type to a variable of other (datatype) implicitly they are converted. Here I am providing a utility method that we can use to add elements to an array. Add new value, which sets as the first value, to existing array. You can declare an array just like a variable −, You can create an array just like an object using the new keyword −, You can initialize the array by assigning values to all the elements one by one using the index −.
