Java Conditional Statements

Conditional Statements

• A conditional statement checks if a conditions is met, and acts based on if it is met or not

  • The condition could be comparing two values, checking if two values are equal, etc.

• The if statement

  • An if statement allows a program to enter a body of code if the condition presented is met
  • E.g. suppose we have the following situation

   	int x = 5;
   	int y = 10; 
               int z = 0;
   	
   	if(x > y)
   	{
   		// x was larger than y
                       z = x + y;
   	}
   	if(x < y)
   	{
   		// x was smaller than y
                       z = x - y;
   	}   
   	if(x == y)
   	{
   		// do even MORE stuff
                       z = x * y;
   	}

  • Which of these would execute?

• Conditions we could use include

  • Greater Than                                     >
  • Less Than                                          <
  • Greater Than or Equal to                  >=
  • Less Than or Equal to                       <=
  • Equal                                                 ==
  • Not Equal                                           !=
