Question

String A= “45”, B= “90”;

String D= A+B+ “200”;

int x= Integer.parseInt(A);

int y= Integer.parseInt(B);

int d= x+y;

System.out.println(“Result 1=” +D);

System.out.println(“Result 1=” +d);​

Answer 1

Answer:

x+y

= 200+ 90

= 290.

is the correct answer .

Thank you .

Good night

Answer 2

$\huge\underline{Given}$

• A="45"
• B="90"

• D=A+B+"200";

Here A and B are string variable even if they are storing numbers so instead of getting added, it will get concatenated.

D="45"+"90"+"200"

= "4590200"

//Strings get concatenated, numbers (in data types : short, int, float, long, double) are added

int x= Integer.parseInt(A);

int y= Integer.parseInt(B);

• Integer.parseInt() converts string to integer
• so x and y storing integer number of A and B
• so x and y id 45 and 90 respectively but in integer data type.

d=x+y

= 45+90

= 135

• Remember:- Java is case-sensitive language so d and D are different.

Output:-

Result 1=4590200

Result 1=135
