Write a method sameDashes that takes two Strings as parameters and that returns whether or not they have dashes in the same places (returning true if they do and returning false otherwise). For example, below are four pairs of Strings of equal length that have the same pattern of dashes. Notice that the last pair has no dashes at all.
string 1: "hi--there-you." "-15-389" "criminal-plan" "abc"
string 2: "12--(134)-7539" "-xy-zzy" "(206)555-1384" "9.8"
To be considered a match, the Strings must have exactly the same number of dashes in exactly the same positions. The Strings might be of different length. For example, the following calls should each return true:
sameDashes("1st-has-more characters", "2nd-has-less")
sameDashes("1st-has-less", "2nd-has-more characters")
because the Strings each have two dashes and they are in the same positions. But the following calls should each return falsebecause the longer string has a third dash where the shorter string does not:
sameDashes("1st-has-more-characters", "2nd-has-less")
sameDashes("1st-has-less", "2nd-has-more-characters")
Method problem: For this problem, you are supposed to write a Java method as described. You should notwrite a complete Java class; just write the method(s) described in the problem statement.

Java is a programming language and computing platform first released by Sun Microsystems in 1995. It has evolved from humble beginnings to power a large share of today’s digital world, by providing the reliable platform upon which many services and applications are built. New, innovative products and digital services designed for the future continue to rely on Java, as well.Java is fast, secure, and reliable.

Comparing the following two strings
String string1 = "two-twenty-nine"
String string2 = "ten-forty-five and I'm hungry."
with the above criteria would return true. It doesn't matter whether one string is longer than the other.
Any assistance would be appreciated!
I have tried:
- converting the strings to char arrays and then comparing the indexes
- Using String. index Of() for each string, and then creating a variable int new Start = String. index Of() with the index of the previous dash as the new starting point to look from

int count = 0;
char index1 = ' ';
char index2 = ' ';
char dash = '-';
char[] string1Array = string1.toCharArray();
char[] string2Array = string2.toCharArray();

Can scratch cloud variables save across computers? For example, if I save the cloud variable as 10, then log in from a different computer will that variable save from that other computer?
Answer:
Explanation:
Scratch cloud variables are a feature in Scratch, a visual programming language, that allows for saving and sharing data across different projects and even across different computers. Once a variable is saved as a cloud variable, it can be accessed from any other project that has been shared with the same Scratch account.
If you set the value of a cloud variable to 10 on one computer, and then log in to Scratch from a different computer using the same Scratch account, you will be able to access the variable and its value (10) from that other computer.
It is important to note that the cloud variable feature is only available for Scratch accounts with a login, if you don't have a Scratch account, you won't be able to use this feature.
It's also good to keep in mind that if you set a variable as a cloud variable in a project, it will be accessible to anyone who has access to that project. So make sure you understand the sharing settings and permissions before using cloud variables in a project that contains sensitive information.
