Question

private void btnUserActionPerformed(java.awt.event.ActionEvent evt) {                                        
   String strName,strFood,strAge; 
   strName=this.txtDogsname.getText();
   strFood=this.txtDogsfood.getText();
   int age= Integer.parseInt(txtDogsage.getText());
   //Changes string to int
   this.lbloutput.setText("The Dog's name is "+strName+". "+ strName+"'s favourite food is "+ strFood+". "+strName+"'s Age in human years is"+(age*7);" years old.");
}   

似乎找不到我错过的地方。 我在这里先向您的帮助表示感谢。

this.lbloutput.setText（“狗的名字是” + strName +“。” + strName +“的最爱食物是” + strFood +“。” + strName +“的人类年龄是” +（年龄* 7）;“岁。”）；

^似乎是问题的线

Answer 1

换线

this.lbloutput.setText("The Dog's name is "+strName+". "+ strName+"'s favourite food is "+ strFood+". "+strName+"'s Age in human years is"+(age*7);" years old.");

至

this.lbloutput.setText("The Dog's name is "+strName+". "+ strName+"'s favourite food is "+ strFood+". "+strName+"'s Age in human years is"+(age*7)+" years old.");

"+(age*7);" years old" "+(age*7);" years old" 。 ;是问题所在。使用+串联不正确。

Answer 2

您正在使用； 之后(age*7) 。 删除它并添加+ ，它应该可以工作
