what is the difference between arrays and strings at java?

a String is one Object (of the type String). an array is a small collection of Objects.

for instance: you know you need to keep seven String-Objects, containing the days of the week, in your program.

String dayOne = "Monday";
String dayTwo = "Tuesday";
...
like here above, this are seperate Objects of the type String.

if you would use:

String week[] = {"Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"};

then, you have one array, containing seven String Objects.

now you can use:

dayOne = week[0];

=> this will load the first element of the array into the variable with the name dayOne.

Strings aren't arrays, arrays aren't strings.

What he said. They have absolutely nothing in common.

Maybe you meant what is the difference between a Variable and an Array?

Because essentially an Array is a variable, which can contain a multiple number of expressions.

But, to answer what you're asking, a String is like a sentence, for example:
"This is a string."

An Array is exactly what I stated above, it's a variable that contain multiple numeric values, or technically I guess it could be used to store anything, and more than one!

For example:

Normal Variable - Array -
