max of all elements of array in java code example

Example 1: max in array java

// Initializing array of integers 
        Integer[] num = { 2, 4, 7, 5, 9 }; 
// using Collections.min() to find minimum element 
        // using only 1 line. 
        int min = Collections.min(Arrays.asList(num)); 
  
        // using Collections.max() to find maximum element 
        // using only 1 line. 
        int max = Collections.max(Arrays.asList(num));

Example 2: how to get the max value of an array java

public static double arrayMax(double[] arr) {
    double max = Double.NEGATIVE_INFINITY;

    for(double cur: arr)
        max = Math.max(max, cur);

    return max;
}
