How to check whether the variable name contains a string, and then output the string variable content

So I have these four variables

private final String PROG_DEPT = "PROGRAMMING/ENGINEERING";
private final String DES_DEPT = "DESIGN/WRITING";
private final String ART_DEPT = "VISUAL ARTS";
private final String SOUND_DEPT = "AUdio";

What I want to do is take a string and compare it with the variable, and then output the contents of the variable (if it is equal to it)

For example, if my string is equal to "art_dept", it checks whether there is a string named art_ The variable of dept, and then output "visual arts"

I want to put it in a 2D string array or list, but I'm not sure how to do what I want to do

Solution

The data type you are looking for is map < string, string >

Map<String,String> departmentNames = new HashMap<String,String>();
departmentNames.put("PROG_DEPT","PROGRAMMING/ENGINEERING");
departmentNames.put("DES_DEPT","DESIGN/WRITING");
//...etc...

//...

String dept = "PROG_DEPT";
String deptName = departmentNames.get(dept);
System.out.println(deptName); //outputs "PROGRAMMING/ENGINEERING"

Map binds unique keys to values In this case, both have a string type Use put (key, value) to add the binding, and use get (key) to get the binding of the key
