import com.bruceeckel.util.*; import java.util.*;
public class FillingArrays { public static void main(String[] args) { int size = 6; // Or get the size from the command line: if(args.length != 0) size = Integer.parseInt(args[0]); boolean[] a1 = new boolean[size]; byte[] a2 = new byte[size]; char[] a3 = new char[size]; short[] a4 = new short[size]; int[] a5 = new int[size]; long[] a6 = new long[size]; float[] a7 = new float[size]; double[] a8 = new double[size]; String[] a9 = new String[size]; Arrays.fill(a1, true); Arrays2.print("a1 = ", a1); Arrays.fill(a2, (byte)11); Arrays2.print("a2 = ", a2); Arrays.fill(a3, 'x'); Arrays2.print("a3 = ", a3); Arrays.fill(a4, (short)17); Arrays2.print("a4 = ", a4); Arrays.fill(a5, 19); Arrays2.print("a5 = ", a5); Arrays.fill(a6, 23); Arrays2.print("a6 = ", a6); Arrays.fill(a7, 29); Arrays2.print("a7 = ", a7); Arrays.fill(a8, 47); Arrays2.print("a8 = ", a8); Arrays.fill(a9, "Hello"); Arrays2.print("a9 = ", a9); // Manipulating ranges: Arrays.fill(a9, 3, 5, "World"); Arrays2.print("a9 = ", a9); } } ///:~
the Problems are: FillingArrays.java [25:1] cannot resolve symbol symbol : method fill (boolean[],boolean) location: class Arrays Arrays.fill(a1, true); ^ /*....*/
FillingArrays.java [44:1] cannot resolve symbol symbol : method fill (java.lang.String[],int,int,java.lang.String) location: class Arrays Arrays.fill(a9, 3, 5, "World"); ^ 10 errors Errors compiling main.
