I think, I have a problem with this (System.out.printf( "Sum is %d\n",
sum);)and also I have problem using import (java.util.Scanner;)
Plese tell me how to resolve problem. The program and out put is
// Addition program that displays the sum of two numbers
import java.util.Scanner;
public class Addition {
public static void main(String[] args) {
//main method begins execution of java application
Scanner input = new Scanner( System.in );
int number1;
int number2;
int sum;
System.out.print("Enter first integer");
number1 = input.nextInt();
System.out.print( "Inter Second Integer");
sum = number1 + number2;
System.out.printf( "Sum is %d\n", sum);
}
}
Out put is the following
Exception in thread "main" java.lang.Error: Unresolved compilation
problem:
The method printf(String, Object[]) in the type PrintStream is not
applicable for the arguments (String, int)
at Addition.main(Addition.java:24)

After that brief diversion into bringing everyone up to speed on the
"advances" of Java 5...
Sounds like your Eclipse is not actually enabling the Java 5
capabilities. How about going Help => About Eclipse SDK => Configuration
Details, then scroll down and tell us the java.runtime.name and
java.runtime.version.
Assuming all is well there (you're actually using Java 5... I don't know
how many people I've seen install Java 5 but not actually be running
it... Eclipse doesn't "magically" know it's there... it has to be on the
path at start-up or specified on the -vm line or in the preferences), go
to Window => Preferences... => Java => Compiler and tell us what the JDK
Compliance, Compiler compliance level says (should be 5.0).
5.0 is required for Scanner and C-like printf.

Very Sorry. That's the second time I have been caught out by that. I
happen to be one of those who subscribe to the heretical view that 1.4 is
good enough, and 1.5 breaks too many eggs. This may be one of them.
