java - When updating JLabel, previous text stays, and old text is placed on top of it -

so, i'm making program, , on program, displays health in format:

health : 82/82 

when take damage, ask program update jlabel, , display took damage this

health: 60/82 

the jlabel public variable, , being created once,

public jlabel uihealth = new jlabel(); 

and on updated below code. here code use update uihealth jlabel updating text after action occures:

uihealth.settext("health: "+health+"/"+playerhealthbar.getmaximum()+""); 

is there simpler way display text updated? matter frame , panels set transparent see image behind acts hud? here code applied transparent, still interactive.

public color clear = new color(0,0,0,0); 

and of course call clear when using .setbackground component.

here image of after taking bit of damage (4-5 hits) looks on ui. (take note of how text stacks on top of itself)

thanks in advance time. please let me know , ask me if seems unclear, or need other snippets of program.

you have jpanel adding label to. need call mypanel.setopaque(false); after creating it.
