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);
}
