How do you find the index of smallest number in an array?

4 Answers

Initialize the minimum value with the first element of your array.
Initialize the corresponding index to 0 (arrays are 0 base indexed)
Loop in your array.
If you find a number smaller than the minimum value, update the minimum value with the value found.

How do you find the second smallest element in an array?

Java program to find the 2nd smallest number in an array

Compare the first two elements of the array.
If the first element is greater than the second swap them.
Then, compare 2nd and 3rd elements if the second element is greater than the 3rd swap them.
Repeat this till the end of the array.

What is the maximum length of an array in Java?

The maximum length of an array in Java is 2,147,483,647 (the maximum size of an int, 2 31 − 1). This limit is not explicitly stated in the JLS but implied by the fact that in an array creation, the length expression must be of type int. 15.10 Array Creation Expression.

What is the maximum value in Java?

When we need bigger range of values, we could use long values. In Java, Long values is represented in 64 bits. However, even if this can hold bigger range of values, there is still a limit to it’s maximum value. The Java Long Max Value is 9,223,372,036,854,775,807.
