}
}
public class Supplementary{
public static void main(String[]args){
Watoto c= new Wazazi();
c.doSomething();
}
}
class Watoto{
public void doSomething(){
System.out.println("Children cry");
}
}

Define this terms and provide an example.
Array and Multidimentional array.

Correct if there is any error and state what will be the output
public class Test2D{
public static void main(String[]args){
int[][]m={
{15,25,35},{35,45,50}
}
int sum;
sum=0;
for(int i=0;i<2;i++)
for(int j=0;j<2;j++)
sum+=m[i][j];
System.out.println(sum);
}
}

Java has three type of control structure discuss them and provide one example for each.

Differentiate betwween the following control loop if and nested if

Write the following code into condition operator
if(gender==1)

Add variable sum, and assign the result to variable sum.
Print "The sum is:", followed by the value of the variable sum.

What is the output of the following programs
Prog#1
public class Break Test{
public static void main(String[]args){
int count;
for(count=1; count≤20; count++){
if(count==8)
break;
System.out.println(count);
}
}
}

Prog#2
public class ContinueTest{
public static void main(String[]args){
for(int count=1;count≤10;count++){
if(count==5)
continue;
System.out.println(count);
}
}
}

What will be the out put of the following for-loop ?
for(int i=1; i<7; i++){
System.out.println(i);

Data type are categorized into two , mention and differentiate them.
