Inserting string array value in for loop in java
I know this is a very simple thing, but I can't see any examples of doing this with strings. This is beyond the basic exercise in my self imposed homework, and more advanced, but I know it can be done so I just want to go ahead and learn these arrays :-D
I'm trying to change the value if the string in the GLabel below:
private void printSubclassBoxes(){
String[] anArray = {"GraphicsProgram", "ConsoleProgram", "DialogProgram"};
int coordinateX = ((getWidth() - BOX_WIDTH) /4);
int otherCoordinateX = coordinateX;
for ( int i = 0 ; i < 3; i++){
double coordinateY = (getHeight() / 2); 开发者_JAVA技巧
GRect classBox = new GRect (coordinateX, coordinateY, BOX_WIDTH, BOX_HEIGHT);
GLabel classLabel = new GLabel ("ARRAY WILL GO HERE");
double labelCoordinateX = (coordinateX + ((classBox.getWidth() / 2) - (classLabel.getWidth() / 2)));
double labelCoordinateY = (coordinateY + ((classBox.getHeight() / 2) + (classLabel.getAscent() / 2)));
add(classBox);
add(classLabel, labelCoordinateX, labelCoordinateY);
coordinateX = otherCoordinateX + coordinateX;
}
}
Thanks for the help!
I think you want this:
GLabel classLabel = new GLabel (anArray[i]);
