Conditional Statements in Java
What are Conditional Statements?
Conditional statements in Java allow programs to make decisions and execute code selectively based on boolean conditions (true or false). They are fundamental for implementing decision-making logic in any program.
When a condition is met, a particular block of code runs. If not, it may be skipped or an alternative block may execute — depending on the structure used.
Conditional statements often use logical operators like:
- && (AND)
- || (OR)
- ! (NOT)
To combine or modify multiple conditions.
And relational operators like >, <, ==, <= and >=.
Types of Conditional Statements in Java
| Statement | Use Case |
|---|---|
| if | Execute a block only if condition is true |
| if-else | Either execute one block or another |
| if-else-if | Choose between multiple conditions |
| switch | Select one block from many based on value |
Summary:
- Conditional statements enable branching in your program flow.
- Conditions are usually boolean expressions using comparison (with the help of relational operators) and logical operators.
- The most common are if, if-else, if-else-if, and switch.
- These structures help programs respond to different inputs or situations.
