How to take a user input in java with the help of conditional statements.

Tomorrow is my project and l have to make a conditional statement. But how to connect scanner class with conditional statement. For example-

import java. util. Scanner;
Scanner sc = new Scanner(System. in);
System. out. println ("Enter your age : ");
int age = sc. nextInt();

System. out. println ( 2 * age);

Now here the output comes Enter your age and when l type my age means any number it multiplies it by 2. So in the same way l want that with conditional statements and logical operators - if, else, else if. I want that it ask my grade and when l enter my grade it says like this---

What I have tried:

--char grade = 'A';

if ( grade == 'A') {
System. out. println ("your grade is A");
} else if ( grade == 'B' ) {
System. out. println ("very good, keep learning ");
} else if ( grade == 'D' ) {
System. out. println ("keep improving ");
} else {
System. out. println (" invalid grade");
}

So this a program so l want that when l run it then first it will ask enter your grade as l told previously and when l will enter it it will tell the result. So this was just an example really l wanted to make that it will ask two things name and age in the consol then after entering that it will act accordingly. Please help me. I'll be remembering your help as tomorrow is my project submission. Please tell me the syntax of that. Love codeproject

I do not understand how name and age are related to grade, however:

Java

Scanner sc = new Scanner(System. in);
System.out.print("Enter your name : ");
String name = sc. next();
System.out.print("Enter your age : ");
int age = sc. nextInt();
System.out.printf("Hi %s, you are %d years old, it's time you learned Java%n", name, age);

Sir you mean to say that l will type import java. util. Scanner;
Scanner sc = new Scanner(System. in);
System. out. println ("Enter your age : ");
int age = sc. nextInt();

Yes.

And also l will type
String name = sc. next();
System.out.print("Enter your age : "); and then l will do this --
char grade = 'A';

if ( grade == 'A') {
System. out. println ("your grade is A");
} else if ( grade == 'B' ) {
System. out. println ("very good, keep learning ");
} else if ( grade == 'D' ) {
System. out. println ("keep improving ");
} else {
System. out. println (" invalid grade");
}
