CH7 – Generating Tables

  1. Create a new class named GeneratingTables.
  2. Create a method named generateTable that takes no parameters.
public static void generateTable(){
  int i = 1;
  while (i < 10){
    double x = (double)i;
    System.out.println(x + "     " + Math.log(x));
    i = i + 1;
  }
}
  1. Add a main method and code in main that calls generateTable.
public static void main(String[] args){
  generateTable();
}

The completed class should appear as follows.

public class GeneratingTables {
  public static void generateTable(){
    int i = 1;
    while (i < 10){
      double x = (double)i;
      System.out.println(x + "     " + Math.log(x));
      i = i + 1;
    }
  }
  public static void main(String[] args){
    generateTable();
  }
}
  1. Compile and run the program.
$ javac GeneratingTables.java
$ java GeneratingTables
