See full list on freecodecamp.org See this code snippet used to find the maximum number using the ternary operator in Java: 1. int num1 = 34; 2. int num2 = 3; 3. int maxNum = num1 >= num2 ? num1 : num2; If the num1 value is larger than or equal to the num2 value. the ternary operator will return the num1, else it will return the value in num2.The ASCII value of a is: 97. In the above program, character a is stored in a char variable, ch. Like, double quotes (" ") are used to declare strings, we use single quotes (' ') to declare characters. Now, to find the ASCII value of ch, we just assign ch to an int variable ascii. Internally, Java converts the character value to an ASCII value.See full list on freecodecamp.org
