Java while循环根据变量x的输入打印“+”

Question

I want to be able to make a statement that prints (in this case "+") based upon the input of variable x. Example: If someone writes that x = 3, then it should print out "+++".

public static void runLoop(int x){
    
    while(//Code//){
        System.out.print("+");
    }
}

Answer 1

if you want while loop and not for loop you may do this:

public static void runLoop(int x){
    
    while(x--!=0){
        System.out.print("+");
    }
}

Explanation :
the x-- return the current value of x and only then decrease it by one so the code will be executed x times.

NOTE:
x-- overrides x value so if you want to keep the value simply use a temporary variable.
