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:']'预计为
expectedResults [0] = new boolean [] {false,false}; // 00B
^
test.java:3:';'预计
expectedResults [0] = new boolean [] {false,false}; // 00B
^
test.java:3:非法启动类型
expectedResults [0] = new boolean [] {false,false}; // 00B

test.java:3:期待

必须在方法中!

语法为:
expectedResults[0] = new boolean[]{false, false};
另外,请确保在方法或静态初始化块中执行赋值。

您可以创建一个类似于此{false, false}
的数组,只有当您将其与变量(Array constants can only be used in initializers
)放在同一行时才会生成:
boolean[] expectedResults = {false, false}; // complies
虽然这不能编译:
boolean[] expectedResults;
expectedResults = {false, false}; // does not complie
改为使用:
boolean[] expectedResults;
expectedResults = new boolean[]{false, false};

这是8x2布尔数组初始化变得容易。
public boolean[][] expectedResults = {
{false, false},
{false, false},
{false, false},
{false, false},
{false, false},
{false, false},
{false, false},
{false, false},
};
这是一个简单的4x8布尔数组初始化。
public boolean[][] expectedResults = {
{false, false, false, false, false, false, false, true},
{true, false, false, false, false, false, false, true},
{true, false, false, false, false, true, true, true},
{false, true, true, true, true, true, true, false}
};

我认为你必须像这样初始化数组。
boolean[][] expectedResults;
expectedResults = new boolean[8][2];
