You should read "how to get started" with Codechef. Link is given on Practice page. By the way, Here T is no of test cases that means you have to answer T times so you should use a loop that runs T times. And again see the output format. Every time you should print the sum in new line. And don't print anything extra that will lead to a wrong answer. In your case, printing "user input addition is conpleted" is not expected. So remove that line. Another mistake is, you are scanning a then b then T. But see the input format, First T is given, Then T times, a and b are given.
So what you need is
1) Scan T
2) Put a loop for T test cases
3) Read a and b for each iteration of loop
4) Print the sum and go to next line
5) Remove System.out.println("user input addition is conpleted");
I hope this helps!!!

// can anyone tell me what is wrong here. import java.util.; import java.lang.; import*;

/ Name of the class has to be "Main" only if the class is public. / class Codechef { public static void main (String[] args) throws java.lang.Exception { Scanner sc=new Scanner(; int t=sc.nextInt(); if(t>=1&&t<=1000) { for(int i=1;i<=t;i++) {
int sum; int a=sc.nextInt(); int b=sc.nextInt(); if(a>=1 &&a<=10000 && b>=1 && b<=10000) { sum=a+b; System.out.println(sum); } }
