syntax - Java controlf and escape sequences -

i'm trying skip line using escape sequence, code looks like

system.out.printf("number of students: " + numberofstudents "\n"); 

but getting error says "syntax error on token ""\n"", delete token"

i same error when trying

system.out.printf("number of students: %c", numberofstudents "\n"); 

this code works i'm trying understand did wrong

system.out.printf("number of students: %d \n", numberofstudents ); 

is there rule against using escape sequences after referencing variable?

thanks

this:

numberofstudents "\n" 

isn't valid. you've got 2 tokens there - identifier , string literal - space between them. that's not valid. use concatenation:

system.out.printf("number of students: " + numberofstudents + "\n"); 

if want... can't put string literal @ end that.

i suggest final code cleanest anyway, although i'd remove space before line break. alternative let println put line break on you:

system.out.println("number of students: " + numberofstudents);
