    public Animace() {
        initComponents();
    }


    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">

        jPanel1 = new javax.swing.JPanel();
        jButton1 = new javax.swing.JButton();
        jButton2 = new javax.swing.JButton();
        jPanel2 = new javax.swing.JPanel();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        jButton1.setText("Play");
        jButton1.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton1ActionPerformed(evt);
            }
        });

        jButton2.setText("Pause");
        jButton2.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton2ActionPerformed(evt);
            }
        });

        javax.swing.GroupLayout jPanel1Layout = new javax.swing.GroupLayout(jPanel1);
        jPanel1.setLayout(jPanel1Layout);
        jPanel1Layout.setHorizontalGroup(
            jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(jPanel1Layout.createSequentialGroup()
                .addContainerGap(javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
                .addGroup(jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
                    .addComponent(jButton1, javax.swing.GroupLayout.Alignment.TRAILING)
                    .addComponent(jButton2, javax.swing.GroupLayout.Alignment.TRAILING))
                .addContainerGap())
        );
        jPanel1Layout.setVerticalGroup(

                .addComponent(jButton2)
                .addContainerGap(237, Short.MAX_VALUE))
        );

        getContentPane().add(jPanel1, java.awt.BorderLayout.LINE_END);

        javax.swing.GroupLayout jPanel2Layout = new javax.swing.GroupLayout(jPanel2);
        jPanel2.setLayout(jPanel2Layout);
        jPanel2Layout.setHorizontalGroup(

        getContentPane().add(jPanel2, java.awt.BorderLayout.CENTER);

        pack();
    }// </editor-fold>

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
     // PLAY BUTTON


    }

    private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
        //PAUSE BUTTON
    }


    public static void Hi(){
       System.out.println("Hi guys");
    }

    public static void main(String args[]) {

        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new Animace().setVisible(true);
            }
        });
    }
    // Variables declaration - do not modify
    private javax.swing.JButton jButton1;
    private javax.swing.JButton jButton2;
    private javax.swing.JPanel jPanel1;
    private javax.swing.JPanel jPanel2;
    // End of variables declaration
}

After click on Jbutton1 (play button) need call method Hi(), every 10s.

After click on Jbutton2 (pause button) need pause this call..

Can you help me? I build in java netbeans.

If you plan on changing elements of your GUI inside the repeatedly called function (Hi in your case) you should use javax.swing.Timer:

private javax.swing.Timer timer;

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    timer = new Timer(10*1000, new java.awt.event.ActionListener() {
        @Override
        public void actionPerformed(java.awt.event.ActionEvent e) {
            Hi();
        }
    });
    timer.start();        
}

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
    timer.stop();
}
