Examples


package com.logicbig.example.math;

public class MaxExample {

    public static void main(String... args) {
        findMax(43, 45);
        findMax(-31, 5);
        findMax(-91, -105);
        findMax(Integer.MIN_VALUE, 3);
        findMax(3521, Integer.MAX_VALUE);
    }

    private static void findMax(int a, int b) {
        int maxValue = Math.max(a, b);
        System.out.printf("Math.max(%s,%s) = %s%n", a, b, maxValue);
    }
}

Output

Math.max(43,45) = 45
Math.max(-31,5) = 5
Math.max(-91,-105) = -91
Math.max(-2147483648,3) = 3
Math.max(3521,2147483647) = 2147483647

        System.out.printf("Math.max(%s,%s) = %s%n", a, b, maxValue);
    }
}

Output

Math.max(90.652,90.678) = 90.678
Math.max(-42.95,32.65) = 32.65
Math.max(-2.22,-11.111) = -2.22
Math.max(1.4E-45,-1.25) = 1.4E-45
Math.max(310.25,3.4028235E38) = 3.4028235E38




package com.logicbig.example.math;

import java.util.Arrays;

public class MaxExample4 {

    public static void main(String... args) {
        double[] values = {123545d, 710129d, 426561d, 354568d};
        System.out.println(Arrays.toString(values));
        double maxValue = values[0];
        for (int i = 1; i < values.length; i++) {

        }
        System.out.println("The maximum value is : " + maxValue);
    }
}

Output

[123545.0, 710129.0, 426561.0, 354568.0]
The maximum value is : 710129.0
