\n The input is provided in the form of a string, separated by spaces or commas.
\n Examples of input data that the program should handle include:
\n \"1, 2, 3, 4, 5\"<\/code>, \"10 20 30\"<\/code>, which contain arbitrary numbers.\n <\/p>\nInput Format<\/h2>\n

Step 1: Reading Input Data<\/h3>\n
\n String<\/code> type variable to handle it.\n <\/p>\nStep 2: Parsing the String<\/h3>\n
\n To do this, you can use the String.split()<\/code> method.\n <\/p>\nStep 3: Converting Strings to Integers<\/h3>\n
Integer.parseInt()<\/code> method.\n <\/p>\nStep 4: Calculating the Sum<\/h3>\n
\n Sum each number using a for<\/code> loop.\n <\/p>\nJava Code Example<\/h2>\n
\n
\nimport java.util.Arrays;\n\npublic class SumOfNumbers {\n public static void main(String[] args) {\n String input = \"5, 10, 15, 20\";\n int sum = sumOfNumbers(input);\n System.out.println(\"Sum of numbers: \" + sum);\n }\n\n public static int sumOfNumbers(String input) {\n \/\/ Splitting the string\n String[] numbers = input.split(\"[,\\\\s]+\");\n \/\/ Sum variable\n int sum = 0;\n \/\/ Summing numbers\n for (String number : numbers) {\n sum += Integer.parseInt(number);\n }\n return sum;\n }\n}\n<\/code>\n <\/pre>\nConclusion<\/h2>\n
\n It is very important to learn string processing methods to handle various input formats
\n as part of your coding test preparation.
\n Based on this foundation, we encourage you to challenge more complex problems.\n <\/p>\n
