Okay after you have learned Java programming theory, we are not Who are these terrorists together to create, let's say our own calculator. So how do we do that? So I will first create something like this system, dot o dot print line. That's a one addition. Okay then I play the subtraction. Then I create the division.
Create the multiplication. Okay then this is the number of boys. They put in the input okay. I want to get a user input so I have to use a scanner scan equal new scanner system.in okay by using the scanner class I have to import this Java dot util dot scanner. Okay. So to get the user input you scan the next ah you can get the next lie okay and then stream input quad is on Qaeda I want to print out the in I want to print out the input.
Okay, so Randy's project Okay, I pull one. Okay, I got the APU here is one okay. So I want to create a C edition. So I create I see a method here. When I audition okay EViews. I see.
User input is one input equal equal to one Then I asked the user for to put in the first number. So priests and first number now you scan against scandal. Next lie okay story number one okay and then I will ask for a second number okay please enter second number industry number two okay then I will call the addition in addition number one number two okay then you will see there is an error because I addition is taboada and then string number one is of string and then string number two is string data type. So I need to convert rubber stopper then da da da da dandies ideation return double data type. So I will do something IDs top result equal addition Okay. Now we'll do something like System dot out dot print line yeah poor result Okay, now I will test my code.
Ron Paul J. Okay, so I select one Okay, so you jump out from here. So it seems like these are coding Cody nah come to these I even put here he did not come to this statement here. So, let me debug this program. So I do run run PJ k i create one a lady no come to here. So I have to see what happened to the to the equation so he The no come here K one k did not come here okay
