display array values in a jlabel
advertisements
I would like display the values of my String array in one Jlabel.
I've tried with a loop (for) but, the result is the new letter overwrites the previous. I do not understand how I could displaying the letters following.
labelWord is the variableName of my Jlabel.
String myArray[] = new String[4];
myArray[0] = "h";
myArray[1] = "e";
myArray[2] = "l";
myArray[3] = "l";
myArray[4] = "o";
and my loop :
for (int j = 0; j <= myArray.length; j++) {
labelWord.setText(myArray[j]);
}
Your code does not work because you set the label value with the 1st String, then the second one, then the 3rd one... You need to concatene all your String into one then set the label text with this value:
String value ="";
for (int j = 0; j <= myArray.length; j++) {
value += myArray[j];}
labelWord.setText( value );
Note: you can also use a StringBuilder instead of concatenating directly to the String.
