Complete the constructor in the following program so that it constructs the array data, then copies values from the parameter init into data. Then complete the toString() method.

class Weight
{
private int[] data;

// Constructor
public Weight(int[] init)
{
// Make data the same length
// as the array referenced by init.
data = new

// Copy values from the
// input data to data.
for (int j)
{
data[j] =
}
}

//Print
public String toString()
{

}
}

public class WeightTester
{
public static void main ( String[] args )
{
int[] values = { 98, 99, 98, 99, 100, 101, 102, 100, 104, 105,
105, 106, 105, 103, 104, 103, 105, 106, 107, 106,
105, 105, 104, 104, 103, 102, 102, 101, 100, 102};
Weight june = new Weight( values );
System. out. println( june );
}
}
2.

class Weight
{
. . .

public int average()
{
. . .
}
}

public class WeightTester
{
public static void main ( String[] args )
{
int[] values = { 98, 99, 98, 99, 100, 101, 102, 100, 104, 105,
105, 106, 105, 103, 104, 103, 105, 106, 107, 106,
105, 105, 104, 104, 103, 102, 102, 101, 100, 102};

Weight june = new Weight( values );
int avg = june. average();
System. out. println("average = " + avg );
}
}

Now add another method that computes the average for a range of days. The method header looks like this:

public int subAverage( int start, int end )
