Printing "for" loop interations

Question

Currently I'm stuck. I can't get more than the first interation of the two loops to print out on the same line. I can get the code to print all the interations if I run the loops seperately. But I'm trying to get the output of the two loops to print out side by side.
public class Project
public static void main(String[ ] args)
final double CELSIUS_TABLE_BEGIN = 40.0; // The table's first Celsius temperature
final double CELSIUS_TABLE_END = 31.0; // The table's final Celsius temperature
final double CELSIUS_TABLE_STEP = 1.0; // Increment between temperatures in table
final double FAHRENHEIT_TABLE_BEGIN = 120.0; // The table's first fahrenheit temperature
final double FAHRENHEIT_TABLE_END = 30.0; // The table's final fahrenheit temperature
final double FAHRENHEIT_TABLE_STEP = 10.0; // Increment between temperatures in table
double celsius; // A Celsius temperature
double fahrenheit; // The equivalent Fahrenheit temperature
double celsius1; // The equivalent Celsius temperature
double fahrenheit1; // A fahrenheit temperature
System.out.println(" TEMPERATURE CONVERSION ");
System.out.println("---------------------------------------------");
System.out.println("Celsius Fahrenheit Fahrenheit Celsius");
for (celsius = CELSIUS_TABLE_BEGIN; celsius <= CELSIUS_TABLE_END; celsius -= CELSIUS_TABLE_STEP)
for (fahrenheit1 = FAHRENHEIT_TABLE_BEGIN; fahrenheit1 <= FAHRENHEIT_TABLE_END; fahrenheit1 -= FAHRENHEIT_TABLE_STEP)
fahrenheit = celsiusToFahrenheit(celsius);
celsius1 = fahrenheitToCelsius(fahrenheit1);
System.out.printf( "%6.2fC %9.2fF %12.2fF %10.2fC \n", celsius, fahrenheit, fahrenheit1, celsius1);
System.out.println("---------------------------------------------");
public static double celsiusToFahrenheit(double c)
return (9.0/5.0)*c + 32;
} //end method
public static double fahrenheitToCelsius(double f1)
return (5.0/9.0)*(f1 - 32);
} //end method
} //end class <Project>

Heres an example of how to loop in parallel:
public static void main (String[] args) {
          int j = 5;
          int k = 10;
          for(int m = j, n = k; m > 0 || n > 0; m--, n--) {
               //Print m and n
               if(m > 0 && n > 0) {
                    System.out.printf("m := %5d%10sn := %5d", m,"", n);
               //Print m
               else if (m > 0) {
                    System.out.printf("m := %5d", m);
               //Print n
               else {
                    System.out.printf("%20sn := %5d", "", n);
               System.out.println();
}Output:
m :=     5          n :=    10
m :=     4          n :=     9
m :=     3          n :=     8
m :=     2          n :=     7
m :=     1          n :=     6
                    n :=     5
                    n :=     4
                    n :=     3
                    n :=     2
                    n :=     1Mel
