如何使字符串添加到字符串功能?
这个问题在这里已经有了答案:
我想你想要这样的东西:
public String addLine(String one, String two){
return one+two;
}
注意,这会返回一个字符串,所以在main中做类似的事情:
text = addLine(text, "line1");
确保你创建它作为一种方法:
public class Text {
private String text = "Hello";
public Text(){}
public Text(String text){
this.text = text;
}
public void setText(String text){
this.text = text;
}
public void addLine(String lnToAdd){
text += "n" +lnToAdd ;
}
public String getText(){
return text;
}
}
public class Main {
public static void main(String[] args) {
Text text = new Text("Hello");
System.out.println(text.getText()); //Returns Hello
System.out.println();
text.addLine("Java");
System.out.println(text.getText()); /*Returns Hello
Java*/
}
}
