I had a computer science test on arrays, but I failed it. Here is something relevant to strings.
String str = "Contact lenses";
System.out.println(str.length(. = 14
System.out.println(str.indexOf("lenses"… = 8
System.out.println(str.contains("L". = false
System.out.println(str.substring(2, 7. = ntact
System.out.println(str.substring(10. = nses
Are the following outputs correct?
Added (1). My bad
System.out.println(str.indexOf("lenses"… = 8
