Usage

From source file:MainClass.java

public static void main(String[] args) {

    //Check if a String is a valid number
    System.out.println("Is Number >>> " + NumberUtils.isNumber("123.123"));

}

From source file:MathUtilsTrial.java

public static void main(String[] args) {

    // Check if a String contains only digits
    System.out.println("Is Digits >>> " + NumberUtils.isDigits("123.123"));

    // Check if a String is a valid number
    System.out.println("Is Number >>> " + NumberUtils.isNumber("123.123"));

    // Get MAX value from an array
    System.out.println("MAX >>> " + NumberUtils.max(new double[] { 3.33, 8.88, 1.11 }));
