The advantage is called the String Pool. But before getting into that, I just want to mention that a String in Java is an immutable object that is backed by an array of characters. Now, the Sting Pool is part of a memory man...

April 19, 2024 - Strings in Java are objects which represent a sequence of characters. Java Strings are immutable, which implies their value cannot be changed once they are created. We can use a simple for loop or toCharArray() method to convert string to char array.

You can also initialize (set) the values in the array when you create it. In this case you don’t specify the size of the array, it will be determined from the number of values that you specify. int[ ] highScores = {99,98,98,88,68}; String[ ] names = {"Jamal", "Emily", "Destiny", "Mateo", "Sofia"};

Basic array problems -- no loops.. Use a[0], a[1], ... to access elements in an array, a.length is the length (note that s.length() is for Strings). Allocate a new array like this: int[] a = new int[10]; // length 10 array See the Java Arrays and Loops Help document for help.
