Error: incompatible types

Question

public void init() {
    Container cp = getContentPane();
    cp.setLayout(null);
    cp.setBounds(0, 0, 769, 556);
    cp.setBackground(Color.ORANGE); 
    // Begin componenten

    String arrayWoord[]=new String[10];
    arrayWoord[0] = letterVeld1;
    arrayWoord[1] = letterVeld2;
    arrayWoord[2] = letterVeld3;
    arrayWoord[3] = letterVeld4;
    arrayWoord[4] = letterVeld5;
    arrayWoord[5] = letterVeld6;
    arrayWoord[6] = letterVeld7;
    arrayWoord[7] = letterVeld8;
    arrayWoord[8] = letterVeld9;
    arrayWoord[9] = letterVeld10;

Java 多次给出以下错误：

arrayWoord[0] = letterVeld1;    
                ^
  required: String    
  found:    JTextField

Answer 1

JTextField 和 String 不是一回事。您可能希望从 arrayWoord[0] = letterVeld1.getText().

等文本字段中获取值

此外，您应该将 letterVeld 存储在一个数组中，只需执行 for (int i = 0; i < 10; i++) arrayWoord[i] = letterVelds[i].getText().
