T9-Java algorithms

java algorithm is a procedure for solving a problem in terms of the actions to execute and the order in which these actions execute.

algorithm example:

  1. Start

  2. Declare variables num1, num2 and sum.

  3. Read values num1 and num2.

  4. Add num1 and num2 and assign the result to sum. (sum←num1+num2)

  5. Display sum.

  6. Stop.

now lets make this algorithm into code

first we add the scanner class as we learned previously

and these are the precise steps of our algorithm

 int num1;
		int num2;
		int sum ;

now in order to make our program more user friendly ( not part of the algorithm) we add extra lines

to ask the user to input the values of num1 and num2

so the final code will be like this

 int num1;
		int num2;
		int sum ;
		System.out.println("Enter the first number");
	     System.out.println("Enter the second number");
System.out.println("The sum of the first and second number is : "+ sum);


Pseudocode is an informal language that helps you develop algorithms without having to worry about the strict details of Java language syntax, Pseudocode does not execute on computers.


  • If student's grade is greater than or equal to 60

  • Print "passed"

  • else

  • Print "failed"

we will learn all about this in the next tutorial
