When the program loads, there's already and image for a place holder

ImageIcon icon = new ImageIcon(Path + "Hangman1.jpg");   
JLabel label = new JLabel();
label.setIcon(icon);

Now i know how to write an if statement that prints out the body part

if (guesses >= 1) System.out.print("HEAD ");
if (guesses >= 2) System.out.print("BODY ");
if (guesses >= 3) System.out.print("LEFT ARM ");
if (guesses >= 4) System.out.print("RIGHT ARM ");
if (guesses >= 5) System.out.print("LEFT LEG ");
if (guesses >= 6) System.out.print("RIGHT LEG ");

But instead of using a normal System.out.print i want to call up my images (want the image to change)

就像是

String imageName = null;    

if (guesses >= 1) imageName = "Head.jpg";
if (guesses >= 2) imageName = "Body.jpg";
if (guesses >= 3) imageName = "LeftArm.jpg";
if (guesses >= 4) imageName = "RightArm.jpg";
if (guesses >= 5) imageName = "LeftLeg.jpg";
if (guesses >= 6) imageName = "RightLeg.jpg";

ImageIcon icon = null;
if (imageName != null) {
    icon = new ImageIcon(Path + File.seperator + imageName);
}

label.setIcon(icon);

显然，每个图像都需要相互添加......

更新

正如 PaulBellora 非常友好地指出的那样，前面的示例是满足 OP 要求的最简单的代码更改，但这并不意味着它是正确的

switch (guesses) {
    case 1:
        imageName = "Head.jpg";
        break;
    case 2:
        imageName = "Body.jpg";
        break;
    case 3:
        imageName = "LeftArm.jpg";
        break;
    case 4:
        imageName = "RightArm.jpg";
        break;
    case 5:
        imageName = "LeftLeg.jpg";
        break;
    case 6:
        imageName = "RightLef.jpg";
        break;
}

会是一个稍微好一点的方法。

通过一些巧妙的布局管理，你可以有六个标签，每个身体部位一个......

// Global references to the body parts
public static final ImageIcon RIGHT_LEG_ICON = new ImageIcon(Path + File.seperator + "RightLeg.jpg");
public static final ImageIcon LEFT_LEG_ICON = new ImageIcon(Path + File.seperator + "LeftLeg.jpg");
public static final ImageIcon RIGHT_ARM_ICON = new ImageIcon(Path + File.seperator + "RightArm.jpg");
public static final ImageIcon LEFT_ARM_ICON = new ImageIcon(Path + File.seperator + "LeftArm.jpg");
public static final ImageIcon BODY_ICON = new ImageIcon(Path + File.seperator + "Body.jpg");
public static final ImageIcon HEAD_ICON = new ImageIcon(Path + File.seperator + "Head.jpg");

// Used as fillers to allow the layout manager to maintain the layout
public static final ImageIcon BLANK_LEG_ICON = new ImageIcon(Path + File.seperator + "BlankLeg.jpg");
public static final ImageIcon BLANK_ARM_ICON = new ImageIcon(Path + File.seperator + "BlankArm.jpg");
public static final ImageIcon BLANK_BODY_ICON = new ImageIcon(Path + File.seperator + "BlankBody.jpg");
public static final ImageIcon BLANK_HEAD_ICON = new ImageIcon(Path + File.seperator + "BlanHead.jpg");

...

// Setup the initial state...(probably in the constructor or when the game rests)
rightLegLabel.setIcon(BLANK_LEG_ICON);
leftLegLabel.setIcon(BLANK_LEG_ICON);
rightArmLabel.setIcon(BLANK_ARM_ICON);
leftArmLabel.setIcon(BLANK_ARM_ICON);
bodyLabel.setIcon(BLANK_BODY_ICON);
headLabel.setIcon(BLANK_BODY_ICON);

...

// As the guesses change...
switch (guesses) {
    case 6:
        rightLegLabel.setIcon(RIGHT_LEG_ICON);
    case 5:
        leftLegLabel.setIcon(LEFT_LEG_ICON);
    case 4:
        rightArmLabel.setIcon(RIGHT_ARM_ICON);
    case 3:
        leftArmLabel.setIcon(LEFT_ARM_ICON);
    case 2:
        bodyLabel.setIcon(BODY_ICON);
    case 1:
        headLabel.setIcon(HEAD_ICON);
}

You should create 7 images, each in its own "hangman" state. And load the appropriate image after each failed guess. Replacing the System.out.print("HEAD ") calls with the label.setIcon() call instead.
