Explanation / Answer

1- for(int i=0;i<20;i++)
{System.out.println(names[i]);}

2- for(int i=0;i<100;i++)
numArray2[i]=numArray1[i];

3-String[] array = {"Einstein", "Newton", "Copernicus","Kepler"};

4-

a-String countryName[]=new String[12];
int population[]=new int[12];
b-for(int i=0;i<12;i++)
{System.out.print("Population of country "+countryName[i]+ " is "+population[i]);
}

5-

a-int ID[]=new int[10];
double grossPay[]=new double[10];
b-for(int i=0;i<10;i++)
{System.out.print("Gross pay of Emplyee ID- "+ID[i]+ " is "+grossPay[i]);
}

6-int grades[][]=new int[30][10];

7-int sum=0;
double avg;
for(int i=0;i<30;i++)
{
for(int j=0;j<10;j++)
{
sum+=grades[i][j];
}}
avg=sum/300;
System.out.print("Average of all the ellements of the array is "+ avg);

8-
a-numberArray[0][0]=145;
b-numberArray[8][10]=18;
