Decision Making and Branching Conditional (Decision Making) Statements

Conditional (Decision Making) Statements

In many situations we need to change the order of execution of statement based on some condition. This involves decision making to see whether a particular condition has arrived or not and then direct the computer to execute statements on the basis of the condition.

If Statement

If statement is used to control the flow of execution of the statements. General syntax of if statement is

If (test condition)

{          // Statement block starts here

            Statement a;

            Statement b;

            …………………

}          // Statement block finishes here

            Statement p;

            Statement q;

If the test condition is true then statement block of if statement will be executed otherwise if statement will be skipped and execution will jump to statement p.

Example:

public class IfStatement {

       public static void main(String[] args)

        {

              int marks=70;

             

              if(marks>60)

              {

                     System.out.println(" First Division");

              }

        }

}

The output of this program is:

First Division
