Because the System.out.print.ln of this if is not played

Question

Can someone tell me why my code doesn’t run the System.out.println(""); end if the if returns true .

public static void tabelear (int tabela[][]){


            for(int linha=0;linha < tabela.length; linha++){
                for(int coluna=0; coluna < tabela[linha].length ; coluna++ ){
            System.out.print(tabela[linha][coluna]+"   ");
                if (coluna-1 == tabela[linha].length){
                System.out.println(""); 
            }
        }

Answer 1

If your idea is to make a new paragraph at each end of the line, you could do so:

for (int linha = 0; linha < tabela.length; linha++) {
    for (int coluna = 0; coluna < tabela[linha].length; coluna++) {
        System.out.print(tabela[linha][coluna] + "   ");
     }
     System.out.println("");
}

Answer 2

The line break is not being printada because the condition is wrong.

The last column of the matrix will always be equal to the row size subtracting one and the condition is backwards

public static void tabelear (int tabela[][]){
    for(int linha=0;linha < tabela.length; linha++) {
        for(int coluna=0; coluna < tabela[linha].length ; coluna++ ){
            System.out.print(tabela[linha][coluna] + "   ");

            if (coluna == tabela[linha].length - 1){
                System.out.println(""); 
            }
        }
    }
}

This can be easily simplified to

public static void tabelear2 (int tabela[][]){
    for(int linha=0;linha < tabela.length; linha++) {
        for(int coluna=0; coluna < tabela[linha].length ; coluna++ ){
            System.out.print(tabela[linha][coluna] + "   ");
        }

        System.out.println(""); 
    }
}
