Data Types:
- Primitive types:
- int:
int age = 25;
- double:
double salary = 5000.50;
- boolean:
boolean isTrue = true;
- char:
char grade = 'A';
- int:
- Reference types:
- Classes:
ClassName objectName = new ClassName();
- Arrays:
int[] numbers = {1, 2, 3, 4, 5};
- Interfaces:
interface InterfaceName { ... }
- Classes:
- Primitive types:
Variables:
- Variable declaration and initialization:java
int age = 25; double salary; salary = 5000.50;
- Variable declaration and initialization:
Operators:
- Arithmetic operators:
+
,-
,*
,/
,%
- Assignment operators:
=
,+=
,-=
,*=
,/=
- Comparison operators:
==
,!=
,>
,<
,>=
,<=
- Logical operators:
&&
,||
,!
- Arithmetic operators:
Control Flow:
Conditional statements:
- if-else:java
if (condition) { // code to execute if condition is true } else { // code to execute if condition is false }
- switch-case:java
switch (expression) { case value1: // code to execute if expression matches value1 break; case value2: // code to execute if expression matches value2 break; default: // code to execute if expression doesn't match any case }
- if-else:
Looping statements:
- for loop:java
for (initialization; condition; update) { // code to repeat while condition is true }
- while loop:java
while (condition) { // code to repeat while condition is true }
- do-while loop:java
do { // code to repeat at least once and continue while condition is true } while (condition);
- for loop:
Branching statements:
- break:
break;
- continue:
continue;
- return:
return value;
- break:
Classes and Objects:
- Class declaration:java
public class ClassName { // class members (fields, constructors, methods) }
- Object creation:java
ClassName objectName = new ClassName();
- Class declaration:
Methods:
- Method declaration:java
public returnType methodName(parameter1, parameter2, ...) { // method body return value; // if returnType is not void }
- Method declaration:
Packages:
- Package declaration at the top of the file:java
package com.example.mypackage;
- Package declaration at the top of the file:
Exception Handling:
- try-catch block:java
try { // code that may throw an exception } catch (ExceptionType1 exception1) { // code to handle exception1 } catch (ExceptionType2 exception2) { // code to handle exception2 } finally { // code that always executes,
- try-catch block:
