如何将输出传递给另一个Java类？

public class AnotherClass {
    public void processOutput(String output) {
        // 处理输出
        System.out.println("接收到的输出：" + output);
    }
}

public class MainClass {
    public static void main(String[] args) {
        String output = "这是输出内容";
        AnotherClass anotherClass = new AnotherClass();
        anotherClass.processOutput(output);
    }
}

public class AnotherClass {
    private String output;

    public void processOutput() {
        // 处理输出
        System.out.println("接收到的输出：" + output);
    }

    public void setOutput(String output) {
        this.output = output;
    }
}

public class MainClass {
    public static void main(String[] args) {
        String output = "这是输出内容";
        AnotherClass anotherClass = new AnotherClass();
        anotherClass.setOutput(output);
        anotherClass.processOutput();
    }
}

public class AnotherClass {
    public String processOutput() {
        String output = "这是输出内容";
        // 处理输出
        return output;
    }
}

public class MainClass {
    public static void main(String[] args) {
        AnotherClass anotherClass = new AnotherClass();
        String output = anotherClass.processOutput();
        System.out.println("接收到的输出：" + output);
    }
}
