java – How will I make my character soar solely when it’s pressed as soon as

I’ve scoured via the web to discover a answer of this however that is the one answer that I may discover but it surely cancels the “yMove += jumpingVelocity * deltatime” as quickly as collision shouldn’t be detected anymore thus it immediately simply goes down. If I take away the isJumping the character continues to go up so long as the soar button is pressed.

xMove = 0;
yMove = 0;

if (handler.getKeyManager().left) xMove -= movementVelocity * deltaTime;
if (handler.getKeyManager().proper) xMove += movementVelocity * deltaTime;
if (handler.getKeyManager().soar && onFloor && !isJumping) {
    yMove += jumpingVelocity * deltaTime;
    isJumping = true;
}
else{
   isJumping = false;
}
// gravity
yMove += gravity * deltaTime;

edit:
That is the code that updates the participant place

public void moveX(){


    if (xMove > 0){

        int tx = (int) (x + xMove + bounds.x + bounds.width) / Tile.TILEWIDTH;
        if (!collisionWithTile(tx,(int) (y + bounds.y) / Tile.TILEHEIGHT) && !collisionWithTile(tx,(int) (y + bounds.y + bounds.top) / Tile.TILEHEIGHT) && tx < handler.getWorld().getWidth()){
            x += xMove;
        }
        else{
            x = tx * Tile.TILEWIDTH - bounds.x - bounds.width - 1;
        }
    }
    else if (xMove < 0){
        int tx = (int) (x + xMove + bounds.x) / Tile.TILEWIDTH;

        if (!collisionWithTile(tx,(int) (y + bounds.y) / Tile.TILEHEIGHT) && !collisionWithTile(tx,(int) (y + bounds.y + bounds.top) / Tile.TILEHEIGHT)){
            x += xMove;
        }
        else{
            x = tx * Tile.TILEWIDTH + Tile.TILEWIDTH - bounds.x;
        }
    }
}

public void moveY(){
    if (yMove < 0){
       int ty = (int) (y + yMove + bounds.y) / Tile.TILEWIDTH;

       if (!collisionWithTile((int) (x + bounds.x) / Tile.TILEWIDTH, ty) && !collisionWithTile((int) (x + bounds.x + bounds.width) / Tile.TILEWIDTH, ty)){
           y += yMove;
       }
       else{
           y = ty * Tile.TILEHEIGHT + Tile.TILEHEIGHT - bounds.y;
       }
    }
    else if (yMove > 0){
        int ty = (int) (y + yMove + bounds.y + bounds.top) / Tile.TILEWIDTH;

        if (!collisionWithTile((int) (x + bounds.x) / Tile.TILEWIDTH, ty) && !collisionWithTile((int) (x + bounds.x + bounds.width) / Tile.TILEWIDTH, ty)){
            y += yMove;
            onFloor = false;
        }
        else {
            y = ty * Tile.TILEHEIGHT - bounds.y - bounds.top - 1;
            onFloor = true;
        }

    }

}
