java - can't input value for string? -

i have been trying convert object string , have string value assigned string have defined.

currently have this

public static final string stringthing; 

^ @ beginning of code have pretty said have string haven't assigned value it.

when try convert object string , set string equal unassigned string value "stringthing" keep getting "unexpected type, found value require variable". thing don't understand why can't assign string value stringthing?

for (object student : students) {     system.out.println(student.tostring())=stringthing; } 

i have seen other topics regarding "unexpected type, found value require variable" in saw things orienting around integers, don't understand why isn't legal or okay in java? there syntax-wise don't understand?

system.out.println(...); 

does print string stdout

if want assign student.tostring() stringthing, :

stringthing = student.tostring(); 

and after can :

system.out.println(stringthing);
