		panele.setLayout(null);
 
		one = new JTextField();
		one.setSize(120,30);
		one.setLocation(20,30);
		one.setFont(new Font("Arial",Font.BOLD,24));
 
		two = new JTextField();

		two.setLocation(20,65);
		two.setFont(new Font("Arial",Font.BOLD,24));
 
		three = new JTextField();
		three.setSize(120,30);

		panele.add(three);
		panele.add(check);
 
		check.addActionListener(this);
 
	}
 
	public void actionPerformed(ActionEvent e) {
		try {
 
 
		a = (int) Integer.parseInt(one.getText());
		b = (int) Integer.parseInt(two.getText());
		c = (int) Integer.parseInt(three.getText());
 
 
 
		}catch(Exception e1) {
		JOptionPane.showMessageDialog(null,"Only Numbers","Klaida",JOptionPane.ERROR_MESSAGE);
 
		}
 
		/*
		 * Or triangle exist?? Formul :
		 * a+b > c
		 * a+c > b
		 * c+b > a
		 * 
 
		 */
 
		if (a+b > c || a+c > b || c+b > a) {
			JOptionPane.showMessageDialog(null,"Exist","Atsakymas",JOptionPane.INFORMATION_MESSAGE);
		}  else {
			JOptionPane.showMessageDialog(null,"Not exist","Atsakymas",JOptionPane.INFORMATION_MESSAGE);
		}
 
 
	}
 
 
 
}

So when i put first num like 1, next num like 2 and next num like 100 , program says Triangle exist. How fix it? Can you help me? Thanks

The triangle inequality theorem states that "for any triangle, the sum of the lengths of any two sides must be greater than the length of the remaining side." (Triangle inequality - Wikipedia, the free encyclopedia) This should translate to an AND (&&) relationship between each of the expressions, not OR (||).

You say, i must changed || to && ?
