Displays the number 1 to 4 on the same line in Java

Write an application that displays the number 1 to 4 on the same line, with each pair of

  • adjacent numbers separated by one space. Write the program using the following techniques:
  • (a) Use one System.out.println statement.
  • (b) Use four System.out.print statements.
  • (c) Use one System.out.printf statement.

Display Numbers in java

public class DisplayNumbers
{
	// main method begins execution of Java application
	public static void main(String[] args) 
	{
		// Initialize variable
		int num1 = 1;	// first number set to 1
		int num2 = 2;	// second number set to 2
		int num3 = 3;	// third number set to 3
		int num4 = 4;	// fourth number set to 4
		
		// (a) Use one System.out.println statement.
		System.out.println("Part (a)");
		System.out.println(num1+" "+num2+" "+num3+" "+num4);
		
		System.out.println();
		
		// (b) Use four System.out.print statements.
		System.out.println("Part (b)");
		System.out.print(num1+" ");
		System.out.print(num2+" ");
		System.out.print(num3+" ");
		System.out.print(num4);
		
		System.out.println("\n");
		
		// (c) Use one System.out.printf statement.
		System.out.println("Part (c)");
		System.out.printf("%d %d %d %d", num1,num2,num3,num4);
		
	}	// end method main
	
}	// end class DisplayNumbers

/* Output:
Part (a)
1 2 3 4
Part (b)
1 2 3 4
Part (c)
1 2 3 4
*/

Method 2- Display Numbers In Java

public class DisplayNumbers{
    public static void main(String[] args){
        // single println()
        System.out.println("1 2 3 4");

        // four print()
        System.out.print("1 ");
        System.out.print("2 ");
        System.out.print("3 ");
        System.out.print("4\n");

        // single printf()
        System.out.printf("%d %d %d %d\n", 1, 2, 3, 4);
    }
}
