java - 如何通过循环连续调用方法？

Question

我必须调用它 5 次，它才会像这样打印。

运行:

我将调用此例程 5 次，依此类推...

public class Method2 {

    public static void main(String[] args) {
        call();
    }
    static void call(){
        System.out.println("I will call this routine 5 times");
        for (int = i = 1; i<5; i++); //I don't know what I'm doing here.
    }
}

我是方法新手，我可以调用，但不知道如何将其放入循环中。 提前致谢!

Answer 1

这就是 for 循环的工作原理..

for (initialization; condition; increment/decrement) {
    statement(s) //block of statements
}

so you actually need to place your print statement in {}

static void call() {
        for (int i = 0; i < 5; i++) {
            System.out.println("I will call this routine 5 times");
        }
}

如果您想打印语句5次，您需要启动循环

from 0 to 5 (exclusive), like

for (int i = 0; i < 5; i++){

}

or from 1 to 5 (inclusive)

for (int i = 1; i <= 5; i++){

}
