public static void main(String[] args)

I would like to call the function union and I have to pass to the functions two parameters, means two matrix mat1 and mat2 declared in main function

//-------------------------------

package model;

import java.awt.event.WindowEvent;

import javax.swing.JFrame;

public class Relation
{
public boolean[][] matrix;
private boolean[][] matrix2;
int rows;
int columns;

public Relation(int rows, int columns)
{
this.rows = rows;
this.columns = columns;

System.out.println("Relation Called");

matrix = new boolean[rows][columns];
matrix2 = new boolean[rows][columns];

}

public Relation union(Relation mat)
{
boolean[][] m, p;
m = mat.getMatrix();
Relation result = new Relation(mat.rows, mat.columns);

p = result.getMatrix();

for (int i = 0; i < rows; i++)
{
for (int j = 0; j < columns; j++)
{
if ((matrix[i][j]) || (m[i][j]))
{
p[i][j] = true;
}
}
}
return result;
}

public Relation inverse()
{
boolean[][] m;
m = new boolean[columns][rows];
for (int i = 0; i < rows; i++)
{
for (int j = 0; j < columns; j++)
{
m[j][i] = matrix[i][j];
}
}
Relation mat = new Relation(columns, rows);
mat.setMatrix(m);
return mat;
}

public static void main(String[] args)
{
Relation relation = new Relation(3, 4);

int[][] mat1 = { {1,0,0,0,0},
{0,1,0,0,0},
{0,0,1,0,0},
{0,0,0,1,0},
{0,0,1,0,1},

int[][] mat2 = { {1,1,0,1,0},
{0,1,0,0,1},
{0,0,1,1,0},
{0,0,0,1,0},
{0,0,1,0,1},

};

//calling the function union : paramtere to pass is mat
//how i call it
}
}
