Topic 2 - JETS

Special reference page for String methods












These are really just reference pages ; it is expected that most students will acquire their knowledge of JETS via practical programming lessons.




The purpose of JETS is to prevent students having to learn the whole language and to provide a predictable way of presenting algorithms suitable for students at both SL and HL. Students can answer examination questions using any suitable part of the language. For example, when incrementing identifiers, questions will use:

    x = x + 1;

whereas students will probably write:


This is fine although students should always try to write their responses clearly and unambiguously.

JETS page Index

These pages illustrate the concepts and syntax of JETS/Java. Programming examples will be found on the Java Pages. The index here shows how they correspond (approximately).

Topic JETS Page Program Examples
2.1.1 Language constructs Most of these concepts are introduced in the core java pages - see the java core index.
2.1.2 Apply data types and structures

Page about Strings

2.1.3 Describe data types and structures Arrays, HL Topic 5
2.1.4 Trace algorithms See the arrays page.
2.1.5 Evaluate algorithms Big O notation
2.1.6 Construct algorithms  
2.1.7 Need for searching and sorting  
2.1.8 Search and sort algorithms Searching/sorting
2.1.9 Efficiency of search and sort algorithms - compared  
2.1.10 Efficiency of search and sort algorithms - discussed  
2.1.11 Syntax, logic and run-time errors Errors in programming

What is it?
is the subset of the Java language that students will be expected to know for examination questions and algorithms.

The IBID Press Computer Science book uses JETS.
