Answer:
public class Calculator {
private int total;
private int value;
public Calculator(int startingValue){
// no need to create a new total variable here, we need to set to the our instance total variable
total = startingValue;
value = 0;
}
public int add(int value){
//same here, no need to create a new total variable. We need to add the value to the instance total variable
total = total + value;
return total;
}
/**
* Adds the instance variable value to the total
*/
public int add(){
// no need to create a new total variable. We need to add the value to the instance total variable
total += value;
return total;
}
public int multiple(int value){
// no need to create a new total variable. We need to multiply the instance total variable by value.
total *= value;
return total;
}
//We need to specify which value refers to which variable. Otherwise, there will be confusion. Since you declare the parameter as value, you need to put this keyword before the instance variable so that it will be distinguishable by the compiler.
public void setValue(int value){
this.value = value;
}
public int getValue(){
return value;
}
}

Answer:
c)1e6f28
Explanation:
The integer pointer intpoint2 points to the address 1e6f24.On increasing the inpoint.The intpoint will point to next location and since we know that the memory taken by integers is 4bytes.So the pointer will move to the next location 4 bytes ahead.
1e6f24+4=1e6f28.
Hence the answer is option c.
Answer:
The above code print the text at three times.
Explanation:
- It is because the above code has one loop which executes three times. The loop executes for the value of i = 0,1 and 10.
- when the value of i is 0 then "++i" will increase the value 1 and the text will be printed.
- If the value of i=1, then the value of i is 2 in the second iteration and the again the text is printed, then the if condition gives the true result and the value of i will be 10.
- Then the loop executes for the last time when the value of i is 10.Then the value will be 11 because of the increment operator and the text will be printed for the third time.
- Then the while loop is not true for the 11 value of i and the loop will get terminated.
