Key thing these these numbers should be smaller Okay. I will like to convert these to something like this okay then I will do da ba, resolve and DB resolve one equal resolve one na ba DB resolve to equal resolve to key Y Pooja Victor Dabba is because only Capita data type can be converted to string. Okay, so we look into that. Okay. So for now I will print the result. So System dot out dot println I he's up okay visa DB resolve one dot two screen then by praying the second resolve will be integer integer why I do the integers because I do not want to have any decimal behind.
Okay let's see her system Oh tall green lie freeze up in integer k DB resolve to the to string. Okay so Rhonda Rhonda program now Okay, please enter first number one one poli sci fi, second number two by four okay so the result will be 3.9 for integer Eb three k because integer type 2.4 becomes two, one papaya becomes one. So one plus two is three, so it's 3.9 0.9 will be removed so you only have 3.0 Okay, so this is roughly how this program works. Okay, so this is a scanner object again, first number, I get a second number and I convert these two number into the body type and I add these two numbers together and I put in small lowercase GABA data type T Mobile keys da ba da da type okay and then I convert the lower case type to capital case, double type key, why I convert the lower case double typo capital case, double type, because only in capital K, capital case Wi Fi there is these are dot two string method eBuy chain these two smaller double error okay okay because Small lower case small case data data does not have the.to stream meta.to string methods to convert the double data type to the string data type key, this one integer back is to convert this data data type into integer data okay.
Okay so this is Ravi, why the program calls door So, before I for God slash n slash n is a new lie, the console calculate the new line and then here is another new line and that And then new lion So, we have a slash enesta escape sequence on special characters okay. So, the next slide so now the body data manipulation in the console calculator CODEL sama data manipulation with variables. So, in our C in Java programming, we have all these many of you later K equal is a sign process addition minus is subtraction. This one is more multiplication So, nice deviation This is modulus modulus means we divide to number and then it gives us a remainder the deviation and then we have prosperous is the increment minus minus Easter decrements Okay. So for every MACD one plus two is three if we have a two string value and we use the plus sign is is actually means a concrete giant to string together.
So hollow brass world we have the hello world as a result Okay. Then we have data types conversion, so in Java programming to convert string data type to numeric data types, we use something like da ba da, da ba 1234 5.12. If we are converting from string to let's say, float, then we will be for dot pass fro. If you convert from string to integer it will be integer dot pass integer. Let's say if you want to convert from numeric to string data types, we use the.to string method. In Ba, the data type must be the uppercase k the first letter must be the upper case.
Smaller case. Double data type do not have the.to string method M for float to integer Then we are converting between two numeric data types. So let's say we are converting from data to integer. So let's say data is equal 123, point four, five. And we want to convert these as well value to integer, we just put a bracket and integer s, if we want to convert from Java to let's say a float, and we'll put bracket float inside the bracket, okay. So, this is how we do data types conversion in Java programming.
Okay, we have ran the code just now. And then we that I will say we have come to the end of this chapter. In this chapter, we have discussed sighs bra the essentials of console program, the past of Java guy we have thought about the variables and data types. And we talked about the race. And then finally we talked about the data manipulation and types conversion. In this chapter we drive into the Java programming language essentially spark two
