Answer:

class MinAlgorithm
{
  public static void main ( String[] args ) 
  {
    int[] array =  { -20, 19, 1, 5, -1, 27, 19, 5 } ;
    int   min;

    // initialize the current minimum
    min = array[0]; 

    // scan the array
    for ( int val : array )
    { 
       if (   val < min ) 
         min = val ; 
    }
      
    System.out.println("The minimum of this array is: " + min );
  }
}

Summing the numbers in an Array

Say that you wanted to compute the sum of a list of numbers. You could start with the number on the left, and then proceed left to right through the remaining numbers. Here is a program that implements that algorithm. Its array contains values of type double.

class SumArray
{

  public static void main ( String[] args ) 
  {
    double[] array =  { -47.39, 24.96, -1.02, 3.45, 14.21, 32.6, 19.42 } ;

    // declare and initialize the total
        total =       ;

    // add each element of the array to the total
    for ( int index=0; index < array.length; index++ )
    { 

      total =     ;

    }
      
    System.out.println("The total is: " + total );
  }
}
