    Hey,
    Code has 3 issues. The "main" method in a class must be declared static. ie.[code]public [color=Orange]static[/color] void main(String[] args) {[/code]
    From a static context either a class must be instantiated and its members referenced or static class members used, therefore to conform with the latter approach the following method declaration change is required: [code]private [color=Orange]static[/color] int Factorial(int n) { // added "static" modifier[/code]
    Lastly, a typo will cause an infinite loop, [code]// for (int i = 1; 1 <= n; i++) { // loop control intended to use i not 1
    for (int i = 1; [color=Orange]i[/color] <= n; i++) {[/code]

    regards, se52
