Question

What is the output of the following code?

class minNumber{
static void leastNum(intarr[]){
int least=arr[0];
for(int i=1;i arr[i])
least=arr[i];
System.out.println(least);
}
public static void main(String args[]){
intnumArray[]={100,20,6,2};
leastNum(numArray);
}
}

A.
100
B.
20
C.
6
D.
2

Answer 1

D. 2

Step-by-step explanation:

The given code is a Java program that finds the least number in an array. The program defines a class called "minNumber" and within that class, there is a static method called "leastNum()" which takes an integer array as its parameter. Within the leastNum() method, a variable "least" is initialized with the value of the first element of the array. Then, the program uses a for loop to iterate through the array, starting at the second element. In each iteration of the loop, the program compares the value of the current element in the array to the value of the "least" variable. If the current element is less than the value of the "least" variable, the value of the "least" variable is updated to the value of the current element. After the loop is finished, the program prints the value of the "least" variable which is the least number in the array.

In the main method, an array of integers is created with values {100,20,6,2}. The leastNum() method is called and passed the numArray as an argument. As the least number in the array is 2, the output of the program will be 2.
