What I have tried:

// to find the square of the greater and the square root of the lesser
import java.io.*;
import java.util.*;

public class sc_squareofgreaterandrootoflesser
{
public void main()throws IOException
{
Scanner sc = new Scanner(System.in);
double n1,n2,r1,r2;
System.out.println("Enter the first number: ");
n1 = sc.nextInt();
System.out.println("Enter the second number: ");
n2 = sc.nextInt();
(n1>n2) ? r1 = n1*n1 : r2 = Math.sqrt(n2);
(n2>n1) ? r2 = n2*n2 : r2 = Math.sqrt(n1);
System.out.println("Square of greater = " + r1 );
System.out.println("Square root of the lesser = " + r2);
}
}

You could start by tagging your question with the correct language: Java, not Javascript.

This corrects your syntax errors, but you still need to fix your logic.

Java

Scanner sc = new Scanner(System.in);
double n1,n2,r1,r2;
System.out.println("Enter the first number: ");
n1 = sc.nextInt();
System.out.println("Enter the second number: ");
n2 = sc.nextInt();
r1 = r2 = 0.0;
if (n1>n2) {
    r1 = n1*n1;
}
else
{
    r2 = Math.sqrt(n2);
}
if (n2>n1) {
    r1 = n2*n2;
}
else {
    r2 = Math.sqrt(n1);
}
System.out.println("Square of greater = " + r1 );
System.out.println("Square root of the lesser = " + r2);

To add to what Richard has said ... You should expect to get syntax errors every day, probably many times a day while you are coding - we all do regardless of how much experience we have! Sometimes, we misspell a variable, or a keyword; sometimes we forget to close a string or a code block. Sometimes the cat walks over your keyboard and types something really weird. Sometimes we just forget how many parameters a method call needs.

We all make mistakes.

And because we all do it, we all have to fix syntax errors - and it's a lot quicker to learn how and fix them yourself than to wait for someone else to fix them for you! So invest a little time in learning how to read error messages, and how to interpret your code as written in the light of what the compiler is telling you is wrong - it really is trying to be helpful!

So read this: How to Write Code to Solve a Problem, A Beginner's Guide Part 2: Syntax Errors[^] - it should help you next time you get a compilation error!
