8.3 COMPOUND STATEMENTS
When a group of statements is written within a curly bracket, then it is known as a compound statement. This group
of statements executes together in a sequential manner to provide the result.

These statements are useful for all types of conditional and iterative statements.
For example,

if(a>b && a>c)
{
System.out.println(a+ "is largest");
System.out.println(b + " and" +c+ "are less than" +a);
}
else if(b>a && b>c)
{
System.out.println(b+ "is largest");
System.out.println(a+ "and" +c+ "are less than" +b);
}
else
{
System.out.println(c+ "is largest");
System.out.println(a+ "and" +b+ "are less than" +c);
}

8.4 CONTROL STATEMENTS
As we have already learnt that the control statements control the flow of a program. They determine whether the
statements will be executed or not based on certain conditions.
There are three types of control statements which are as follows:
• Sequential Statements
• Conditional Statements
• Iterative Statements

Let us learn about them in detail.

8.4.1 Sequential Statement Statement 1
In Java, the statements are executed sequentially which represents the default flow of
statements. In the default flow of statements, the compiler executes the first statement and
then goes to the next statement for its execution and so on, unless it receives a conditional Statement 2
or an iterative statement. The sequential statement follows the top-down approach.
The following program shows the sequential flow of statements. Statement 3
