is solved.

        int[] constraintType = {3};
        double[] upperBound = {1.0, 1.0};

        double[] b = {0.5};
        double[] upperLimit = {1.5};
        double[] c = {- 1.0, - 3.0};
        
        DenseLP zf = new DenseLP(a, b, c);
        
        zf.setUpperLimit(upperLimit);

        zf.solve();
        new PrintMatrix("Solution").print(zf.getPrimalSolution());
        new PrintMatrix("Dual Solution").print(zf.getDualSolution());
        System.out.println("Optimal Value = " + zf.getOptimalValue());
    }
}

Output

Solution
    0   
0  0.5  
1  1    

Dual Solution
   0   
0  -1  

Optimal Value = -3.5
