Writing Some More Programs
The programs we have developed so far execute instructions sequentially from top to bottom.
However, there are scenarios where altering the sequence of statement execution is necessary.
Additionally, we may need to repeat certain statements multiple times. Furthermore, there are
cases where we need to terminate the execution of specific statements prematurely. To address
these requirements, we use control flow statements. Java provides three types of control flow
statements, which are as follows:
Conditional Statements Looping Statements Jump Statements
Let us learn about these in detail.
CONDITIONAL STATEMENTS
In Java, conditional statements help the program to make decisions. They allow different code
blocks to be executed depending on whether specified conditions are true or false. This way, the
program determines and executes appropriate actions based on different situations. Conditional
statements are also referred to as decision-making statement.
There are four decision-making statements in Java as follows:
if statement
if … else statement
if … else… if statement
switch statement
Let‘s learn about these decision-making statements in Java.
The if Statement
The if statement is the simplest form of a conditional statement in Java. If the condition in the if
statement is true, the statements inside its body will be executed. If the condition is evaluated as
false, the statements inside the if block will be skipped and execution will move to the next part
of the code.
