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.

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.
