Java obtain the maximum value in an array

Maximum value acquiring: Find the maximum from all the elements of an array.

Realization of ideas:
definition of variables, save the array element on the index 0
iterate, obtaining the array element of each
variable on the traverse to the array of storage elements and compares the index value 0
if the value of the array element is greater than the value of the variable , recorded live in the new variable value of
an array to loop through the end of the saved variable is an array of maximum

 

// find the maximum 
public  class ArrayDemo3 {
     public  static  void main (String [] args) {
         int [] = {1,2,3,4,5,6,6} ARR; // define an array of storage elements designated 

        int ARR = SUM [0]; // assume that the first element is the maximum value of
         // for loop through the array of elements, with each cycle the element array index 0 magnitude comparison 
        for ( int I = 0; I <arr.length ; I ++ ) {
             IF (sum <ARR [I]) { // element in comparison with the sum array, the sum over a large sum assigned to put it as a new comparative value 
                sum = ARR [I]; 
            } 
        } 
        the System.out .println (SUM); // maximum value of the output array
    }
}
