java - 二维 boolean 数组创建和赋值。编译时错误

Question

public class Test {
    boolean[][] expectedResults = new boolean[8][2];
    expectedResults[0] = new boolean[] {false, false}; //00B
}       

给我以下编译时错误:

test.java:3: ']' 预期
expectedResults[0] = new boolean[] {false, false};//00B
^
测试.java:3: ';'预计
expectedResults[0] = new boolean[] {false, false};//00B
^
test.java:3: 类型的非法开始 expectedResults[0] = new boolean[] {false, false};//00B
^test.java:3: 预期 expectedResults[0] = new boolean[] {false, false};//00B
^测试.java:3: ';'预期的 expectedResults[0] = new boolean[] {false, false};//00B
^test.java:3: 类型的非法开始 expectedResults[0] = new boolean[] {false, false};//00B
^test.java:3: 预期 expectedResults[0] = new boolean[] {false, false};//00B
^测试.java:3: ';'预期的 expectedResults[0] = new boolean[] {false, false};//00B
^test.java:3: 类型的非法开始 expectedResults[0] = new boolean[] {false, false};//00B
^test.java:3: 预期 expectedResults[0] = new boolean[] {false, false};//00B
^测试.java:3: ';'预期的 expectedResults[0] = new boolean[] {false, false};//00B
^test.java:4: 需要类、接口(interface)或枚举

已解决

必须在方法中!。

Answer 1

语法是:

expectedResults[0] = new boolean[]{false, false};

此外，请确保在方法或静态初始化 block 中执行赋值。
