Computer Applications Class 10 ICSE CISCE Topics and Syllabus

Variable define state

Operations/methods/messages/ methods define behaviour

•  Primitive data types,
• Composite data types

• Variable declarations for  primitive data types, composite data types
• difference between the primitive data types, composite data types

• invoking the methods with respect to use of multiple methods with different names to implement modular programming
• using data members and member methods
• Actual parameters and formal parameters

• Default constructor
• Parameterized constructor
• Constructor overloading

Class may be considered as a new data type created by the user, that has its own functionality.

• Class as a composite type
• The distinction between primitive data type and composite data type or class types
• Show how classes allow user defined types in programs. All primitive types have corresponding class wrappers.

The following methods are to be covered:

• int parseInt(String s),
• long parseLong(String s),
• float parseFloat(String s),
• double parseDouble(String s),
• boolean isDigit(char ch),
• boolean isLetter(char ch),
• boolean isLetterOrDigit(char ch),
• boolean isLowerCase(char ch),
• boolean isUpperCase(char ch),
• boolean isWhitespace(char ch),
• char toLowerCase (char ch)
• char toUpperCase(char ch)

• Usage of Wrapper Classes with respect to numeric and character data types

• Private access specifiers
• Protected access specifiers
• Public access specifiers

• Visibility rules for private access specifiers
• Visibility rules for protected access specifiers
• Visibility rules for public access specifiers

• Scope of variables
• Scope of  Class variables
• Scope of  Instance variables
• Scope of  Argument variables
• Scope of Local variables

• Sorting techniques - selection sort and bubble sort;
• Search techniques – linear search and binary search, Array as a composite type, length statement to find the size of the array (sorting and searching techniques using single dimensional array only).

The following String class methods are to be covered:
String trim()
String toLowerCase()
String toUpperCase( )
int length( )
char charAt (int n)
int indexOf(char ch)
int lastIndexOf(char ch)
String concat(String str)
boolean equals (String str)
boolean equalsIgnoreCase(String str)
int compareTo(String str)
int compareToIgnoreCase(String str)
String replace (char oldChar,char newChar)
String substring (int beginIndex)
String substring (int beginIndex, int endIndex)
boolean startsWith(String str)
boolean endsWith(String str)
String valueOf(all types)

Programs based on the above methods, extracting and modifying characters of a string, searching for a string using linear search technique.
