    Default What's wrong with the PRINTF statement ?

    Hello guys, i have been trying to play around with System.out.printf , but it says that the method is not applicable to the attributes.. i don't think i am doing anything wrong but i can't understand what's going on.. below is my code :

     
    package com.examples;
     
    import java.util.Scanner;
     
    public class Comparison {
     
    	public static void main(String[] args) {
     
    		Scanner input = new Scanner( System.in );
     
    	      int number1; 
    	      int number2; 
     
    	      System.out.print( "Enter first integer: " ); 
    	      number1 = input.nextInt();  
     
    	      System.out.print( "Enter second integer: " ); 
    	      number2 = input.nextInt();  
     
    	      if ( number1 == number2 ) 
    	         System.out.printf( "%d == %d\n", number1, number2 );
     
    	      if ( number1 != number2 )
    	         System.out.printf( "%d != %d\n", number1, number2 );
     
    	      if ( number1 < number2 )
    	         System.out.printf( "%d < %d\n", number1, number2 );
     
    	      if ( number1 > number2 )
    	         System.out.printf( "%d > %d\n", number1, number2 );
     
    	      if ( number1 <= number2 )
    	         System.out.printf( "%d <= %d\n", number1, number2 );
     
    	      if ( number1 >= number2 )
    	         System.out.printf( "%d >= %d\n", number1, number2 );
     
    	}
     
    }

    and this basic code :

     
     System.out.printf( "%s\n%s\n", 
             "Welcome to", "Java Programming!" );

    for the second statement :

    The method printf(Locale, String, Object[]) in the type PrintStream is not applicable for the arguments (String, String, String)


    and for the class Comparison, it gives the error everywhere where i have printf :

    The method printf(String, Object[]) in the type PrintStream is not applicable for the arguments (String, int, int)

    What version of the JDK are you using?
    How are you compiling the source? Are you using the javac command? If not, try it to get better error messages. The error messages you posted are not very good.

    If you're using Eclipse Kepler SR2, there is a patch for Java 8 you may have to install to avoid these kind of errors. Just search 'eclipse java 8 patch'. Eclipse Luna has Java 8 support built in.
